A catalytic amount of an iron salt and bipyridine ligand in the presence of an organozinc base activates the ortho C-H bond of a carboxamide, and the following reaction with an alkene such as ethylene gas (1 atm), styrene derivatives, and vinylsilane or vinylboron derivatives via carbometalation gives a putative alkylzinc intermediate. This intermediate can be further reacted with electrophiles such as deuterium oxide or allyl bromide. When monosubstituted alkenes are used as a substrate, the linear alkyl product is selectively obtained. The monoalkylated product is exclusively obtained, and dialkylation does not proceed.

Hydroarylation is an environmentally attractive strategy which incorporates all of the atoms contained in the substrates into the desired products. Almost all the hydroarylations of norbornene reported to date involve an exo-selective reaction. Here we show the endo-selective hydroarylation of norbornene in the Rh(I)-catalyzed reaction of aromatic amides. The addition of sterically bulky carboxylic acids enhances the endo-selectivity of the reaction. The results of deuterium-labeling experiments show that both the ortho-carbon and the ortho-hydrogen atoms of aromatic amides were attached to the same carbon atom of the norbornane skeleton in the hydroarylation product. These results clearly suggest that hydrometalation or carbometalation, which are commonly accepted mechanisms for the catalytic hydroarylation of C-H bonds, are not involved as the key step in the present reaction, and suggest that the reaction involves a rhodium carbene complex generated from norbornene as the key intermediate.

The thermodynamics of complex formation of Ni2+ with molecular liquids (ML), dimethyl sulfoxide (DMSO), methanol (MeOH), and acetonitrile (AN) in the ionic liquid (IL) of 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)amide ([C(2)mim][TFSA]) has been elucidated using ultraviolet (UV)-visible spectroscopy. X-ray structural analyses for single crystals grown from Ni2+-[C(2)mim][TFSA]-DMSO and -AN solutions at high ML contents have shown that six DMSO oxygen or AN nitrogen atoms coordinate with Ni2+ to form octahedral structures of [Ni(dmso)(6)](TFSA)(2) and [Ni(an)(6)](TFSA)(2), respectively. This is the same in the case of the Co2+ complex of [Co(dmso)(6)](TFSA)(2). UV-visible spectroscopic experiments have revealed that the TFSA(-) anions that initially combine with Ni2+ in the IL are replaced with ML molecules in the IL-ML systems in three steps with increasing ML content. The electron donicities of the three MLs are larger in the order of DMSO > MeOH > AN. However, the stability of each complex does not simply depend on this order; the stability is higher in the order of [Ni(dmso)(n)] > [Ni(an)(n)](4) [Ni(meoh)(n)]. In other words, the stability of the MeOH complexes is lower than that of the AN ones, despite the higher electron donicity of MeOH. The reasons for the order of the complex stabilities have been interpreted on the molecular scale, according to the stepwise enthalpies Lambda H-n(0) and entropies T Lambda S-0(n) determined, together with the strength of the hydrogen bonding between the MLs and the imidazolium ring and the formation of MeOH clusters in [C(2)mim][TFSA].

Soil salinization and alkalization is one of the most devastating environmental problems, threatening the sustainable development of agriculture. Bio-amelioration using microorganisms such as bacteria is a promising method for the remediation of calcareous sodic and saline-sodic soil due to its high efficiency, low cost and environmental-friendly characteristics. In the present study, a salt resistant bacterium, Bacillus subtilis BSN-1, was isolated from arid region in Xinjiang, China, and its effects on salt crystallization during evaporation crystallization of saline-alkali soil solution were examined. It was found that the fermentation products of B. subtilis BSN-1, such as glutamic acid, significantly lowered the pH of saline soil solution because of the ionization of carboxyl. The complexation between Ca2+ and fermentation products inhibited the precipitation of Ca-P compounds as well, since the binding sites supplied for Ca2+ is one or two orders of magnitude than that for HPO42-. Moreover, the increased content of active phosphate is attributed to the chelation and adsorption exerted through carboxyl and amide bonds. These findings demonstrated that Bacillus subtilis BSN-1 suppressed the crystallization of phosphate and therefor increased the content of active phosphate, which may provide a promising solution for amendment and remediation of saline-alkali soil.

Nineteen amides (three of them unpublished) were synthesized and tested on Tuta absoluta Meyrick (Lepidoptera: Gelechiidae), an important pest of Solanaceae plants worldwide. Three of these compounds (14, 15 and 16) presented high acute toxicity toward the pest, with LD(50)s of 3.68 (CI95 = 2.83 – 4.47), 6.46 (CI95 = 5.85 – 7.20), and 13.52 mu g/mg (CI95 = 11.06 – 15.95), respectively. Amide 14 presented the fastest action (LT50 = 1.2 minutes, CI95 = 1.03 – 1.37), followed by amide 16 (LT50 = 18 minutes, CI95 = 9.96 – 26.04), and amide 15 (LT50 = 3.7 hours, CI95 = 0.69 – 6.71). When applied at a sublethal dose, they did not affect weight gain and leaf consumption of the pest. Bioassays were also conducted using the ant Solenopsis saevissima (Hymenoptera: Formicidae) and wasp Polybia ignobilis (Hymenoptera: Vespidae) to assess the toxicity of the amides against T. absoluta predators. Amides 14, 15, and 16 were harmless to S. saevissima but presented high toxicity toward P. ignobilis. Amides 14, 15 and 16 are potential hit compounds for the development of insecticides for T. absoluta control. However, their use should be carried out following the principles of ecological selectivity to mitigate potential adverse effects on non-target organisms.

AimTo evaluate the remineralization ability of two endodontic sealer cements. MethodologyMid-coronal dentine surfaces were subjected to: (i) 37% phosphoric acid (PA) or (ii) 0.5mol L-1 ethylenediaminetetraacetic acid (EDTA) conditioning prior to the application of two experimental hydroxyapatite-based cements, containing sodium hydroxide (calcypatite) or zinc oxide oxiapatite respectively. Samples were stored in simulated body fluid for 24h or 21days. Remineralization of the dentine surfaces were studied by Raman spectroscopy (mapping with K-means cluster and hierarchical cluster analysis) was undertaken. Nanoroughness and collagen fibril width measurements were performed with an atomic force microscopy. ANOVA and Student-Newman-Keuls test were performed (=0.05). ResultsPhosphoric acid+oxiapatite promoted both the highest dentine mineralization (P<0.05) and crystallographic maturity at the dentine surface. Noncrystalline amorphous-like apatites were also formed. Dentine treated with PA+calcypatite attained the roughest surface (P<0.05) with minimal fibril width (P<0.05). Cross-linking of collagen only became greater in the group PA+oxiapatite after 21days. The maximum relative mineral concentration and structure of collagen linked to the amide I and ratio amide III/AGEs was obtained after using PA+calcypatite at 21-days time-point (P<0.05). EDTA produced a lower stoichiometric hydroxyapatite (P<0.05) with decreased maturity, at the expense of carbonate band widening, although it favoured the nucleation of carbonated calcium phosphate. ConclusionsDentine surfaces treated with PA+oxiapatite attained the highest dentine remineralization with both crystalline-stoichiometric and amorphous apatites, at 21days. EDTA conditioning facilitated amorphous-bulk mineral precipitation. The amorphization was more intense after using oxiapatite and provided an ion-rich environment favouring insitu dentine remineralization.

Intermolecular C-C bond-forming reactions are underdeveloped transformations in the field of biocatalysis. Here we report a photoenzymatic intermolecular hydroalkylation of olefins catalyzed by flavin-dependent ‘ene’-reductases. Radical initiation occurs via photoexcitation of a rare high-order enzyme-templated charge-transfer complex that forms between an alkene, alpha-chloroamide, and flavin hydroquinone. This unique mechanism ensures that radical formation only occurs when both substrates are present within the protein active site. This active site can control the radical terminating hydrogen atom transfer, enabling the synthesis of enantioenriched gamma-stereogenic amides. This work highlights the potential for photoenzymatic catalysis to enable new biocatalytic transformations via previously unknown electron transfer mechanisms.

Recently, mechanical ball milling was applied to chitin depolymerization. The mechanical activation afforded higher selectivity toward glycosidic bond cleavage over amide bond breakage. Hence, the bioactive N-acetylglucosamine (GlcNAc) monomer was preferentially produced over glucosamine. In this regard, the force-dependent mechanochemical activation-deactivation process in the relaxed and pulled GlcNAc dimer undergoing deacetylation and depolymerization reactions was studied. For the relaxed case, the activation energies of the rate-determining steps (RDS) proved that the two reactions could occur simultaneously. Mechanical forces associated with ball milling were approximated with linear pulling and were introduced explicitly in the RDS of both reactions through force-modified potential energy surface (FMPES) formalism. In general, as the applied pulling force increases, the activation energy of the RDS of deacetylation shows no meaningful change, while that of depolymerization decreases. This result is consistent with the selectivity exhibited in the experiment. Energy and structural analyses for the depolymerization showed that the activation can be attributed to a significant change in the glycosidic dihedral at the reactant state. A lone pair of the neighboring pyranose ring O adopts a syn-periplanar conformation relative to the glycosidic bond. This promotes electron donation to the sigma*-orbital of the glycosidic bond, leading to activation. Consequently, the Bronsted-Lowry basicity of the glycosidic oxygen also increases, which can facilitate acid catalysis.

The removal of phenolic compounds from water streams is of great importance due to their high toxicity, car-cinogenicity, and bioaccumulation in food chains. In this study, the separation of four representative phenolic compounds (including phenol (PhOH), p-cresol (MePhOH), p-chlorophenol (ClPhOH), and p-nitrophenol (O2NPhOH)) from aqueous solutions by pervaporation using poly(ether-b-amide) (PEBA) membrane was studied. The effects of feed concentration (up to 0.6 wt%) and operating temperature (30-70 degrees C) on the separation performance were investigated. While the permeation fluxes of phenolic compounds increased at higher feed concentrations, the increase in the flux was less than proportional, leading to a decrease in the enrichment factor. It was also shown that both the permeation flux and the enrichment factor increased with an increase in temperature. However, the permeabilities of the phenolic compounds in the membrane were impacted differently. Of particular interest were the coupling effects of co-existing phenolic compounds due to permeant-permeant interactions, which were found to be significant in permeation of multiple phenolic compounds that were relevant to practical applications. The permeation of PhOH, MePhOH and ClPhOH was all affected adversely by the presence of additional phenolic compounds in the feed solution, while the opposite was true for the permeation of slow-permeating O2NPhOH. Depending on the specific phenol solute, high-purity phenol crystals could be produced from the phenol-enriched permeate via de-sublimation in the cold trap, which was of particular interest for practical applications.

Connector Type-Controlled Mesophase Structures in Poly(propyl ether imine) Dendritic Liquid Crystals of Identical Dendrimer Generations

Poly(propyl ether imine) (PETIM) dendrimers of one to three generations are used as dendritic cores to identify the influence of varying connector types that connect the dendritic core with peripheral mesogens on the emerging liquid crystalline (LC) properties. The LC properties vary in these dendritic liquid crystals, even when the dendrimer generations and thus the number of peripheral mesogenic moieties remain identical. PETIM dendrimer generations one to three, ester and amide connectors varying with succinates, phthalates, and succinamides, are studied herein. Cholesteryl moieties are installed at the peripheries through the above connectors to induce mesogenic properties. These modified dendritic liquid crystals reveal a layered mesophase structure in most ester and amide connector-derivatives, whereas a third-generation phthalate ester dendrimer favors a rectangular columnar mesophase structure. A transition from layered to a rectangular columnar structure results by a mere change in the connector varying between a succinate or succinamide or phthalate, within one particular dendrimer generation and without altering the underlying dendrimer core or the number of mesogenic moieties. The study demonstrates that in dendritic liquid crystals with essentially identical chemical constitutions, a change in the connector type connecting the mesogen with the dendrimer core is sufficient to change the mesophase structures.
