On July 20, 2020, Persson, Ingmar; Lundberg, Daniel; Bajnoczi, Eva G.; Klementiev, Konstantin; Just, Justus; Sigfridsson Clauss, Kajsa G. V. published an article.Computed Properties of 685-91-6 The title of the article was EXAFS Study on the Coordination Chemistry of the Solvated Copper(II) Ion in a Series of Oxygen Donor Solvents. And the article contained the following:

The structures of the solvated Cu(II) ion in H2O and nine organic oxygen donor solvents with similar electron-pair donor ability, but with different space-demanding properties at coordination, were studied by EXAFS. N,N’-Dimethylpropyleneurea and N,N,N’,N’-tetramethylurea are sufficiently space demanding at coordination to make the axial positions not accessible, resulting in square-planar Cu(II) solvate complexes with an intense green color. The mean Cu-O bond distances in these two solvate complexes are 1.939(3) and 1.935(3) Å, resp. The best fits of the remaining solvates, which are light blue in different hues, were obtained with a Jahn-Teller distorted-octahedral model consisting of four strongly bound solvent mols. in the equatorial positions at 1.96(2) Å and two in the axial positions but with different Cu-Oax bond distances: ∼2.15 and 2.32 Å. This is in agreement with observations in solid-state structures of compounds containing hexaaquacopper(II) complexes crystallizing in noncentrosym. space groups and all reported crystal structures containing a [Cu(H2O)5(O-ligand)] complex with Jahn-Teller distortion. Such a structure is in agreement with previous EPR and EXAFS studies proving the hydrated Cu(II) ion to be a noncentrosym. complex in aqueous solution The refinements of the EXAFS data of the solids [Cu(H2O)6](ClO4)2, [Cu(H2O)6](BrO3)2, [Cu(H2O)6]SiF6, Cu(NO3)2·2.5H2O, and CuSO4·5H2O gave Cu-O bond distances significantly different from those reported in the crystallog. studies but similar to the configuration and bond distances in the hydrated Cu(II) ion in aqueous solution This may depend on whether the orientation of the axial positions is random in one or three dimensions, giving a mean structure of the solid with symmetry higher than that of the individual complexes. This study presents the very 1st exptl. data from the new x-ray absorption spectroscopy beamline Balder at the MAX IV synchrotron radiation facility in Lund, Sweden, as well as the used properties of the beamline. The coordination chem. of the solvated Cu(II) ion was studied in 10 solvents, including H2O. The Cu(II) ion has a noncentrosym. Jahn-Teller distorted-octahedral geometry with the axial Cu-O bond distances differing by ∼0.2 Å. The experimental process involved the reaction of N,N-Diethylacetamide(cas: 685-91-6).Computed Properties of 685-91-6

Alsudairi, Amell; Lajami, Amal; Kendrick, Ian; Mukerjee, Sanjeev; Abraham, K. M. published an article in 2019, the title of the article was Correlating ionic conductivity, oxygen transport and ORR with structure of dialkylacetamide-based electrolytes for lithium-air batteries.Category: amides-buliding-blocks And the article contains the following content:

Chem. structures of lithium and tetrabutylammonium (TBA) salt solutions in N,N-dimethylacetamide (DMAc) and N,N-diethylacetamide (DEAc), two high Donor Number organic solvents, were studied. In LiX salt solutions (where X = PF6-, CF3SO3-, ClO4- and NO3-), solvation occurs when the Li+ bonds with the solvent’s carbonyl group forming Li+[O=C(CH3)N(CH3)2]nX- ion pairs. IR and 13C-NMR spectra are consistent with the ion pair being solvent-separated when the anion is PF6-, ClO4- or NO3-, and a contact ion pair in the case of CF3SO3-. Chem. interactions between TBA+ and the solvents to form conducting solutions appeared to be dipolar in nature. Ionic conductivities of TBA+ and Li+ electrolytes were measured and correlated with their viscosities. In 0.1M TBAPF6/DMAc, the O2 solubility and diffusion coefficient (3.09 × 10-6 mol/cm-3 and 5.09 × 10-5 cm2s-1, resp.) measured using microelectrode technique are typical of values measured in several TBA+ solutions Microelectrode voltammetry revealed steady-state limiting current behavior for oxygen reduction reactions (ORR) in TBAX/DMAc electrolytes indicating a reversible ORR process. Conversely, microelectrode current-voltage data for ORR in LiX/DMAc electrolytes revealed irreversible behavior mainly ascribed to the blockage of the electrode surface by insoluble ORR products. The ORR in DMAc correlated with its high Donor Number and the overall process conformed to the Hard-Soft Acid-Base theory. The experimental process involved the reaction of N,N-Diethylacetamide(cas: 685-91-6).Category: amides-buliding-blocks

We report on the use of charge-transfer complexes between amines and carbon tetrachloride, as a novel way to activate the amine for photochem. reactions. This principle is demonstrated in a mild, transition metal free, visible light assisted, dealkylative amide formation from feedstock carboxylic acids and amines. The low absorption coefficient of the complex allows deep light penetration and thus scale(coating process) up to a gram scale.

Azizi, Kobra; Madsen, Robert published an article in 2020, the title of the article was Radical condensation between benzylic alcohols and acetamides to form 3-arylpropanamides.Electric Literature of 685-91-6 And the article contains the following content:

A new radical condensation reaction was developed where benzylic alcs. and acetamides were coupled to generate 3-arylpropanamides ArCH2CH2C(O)NR1R2 [Ar = Ph, 4-ClC6H4, 1-naphthyl, etc.; R1 = R2 = Me, Et; R1 = H; R2 = Me; R1R2 = (CH2)5, (H2C)2O(CH2)2] with water as the only byproduct. The transformation was performed with potassium tert-butoxide as the only additive and gave a variety of 3-arylpropanamides ArCH2CH2C(O)NR1R2 in good yields. The mechanism was investigated exptl. with labeled substrates, trapping experiments and spectroscopic measurements. The findings indicated a radical pathway where potassium tert-butoxide was believed to serve a dual role as both base and radical initiator. The radical anion of the benzylic alc. was proposed as the key intermediate, which undergoes coupling with the enolate of the amide to form the new C-C bond. Subsequent elimination to the corresponding cinnamamide and olefin reduction then afforded the 3-arylpropanamides ArCH2CH2C(O)NR1R2. The experimental process involved the reaction of N,N-Diethylacetamide(cas: 685-91-6).Electric Literature of 685-91-6

On August 31, 2018, Laha, Joydev K.; Patel, Ketul V.; Tummalapalli, K. S. Satyanarayana; Hunjan, Mandeep Kaur published an article.Recommanded Product: 685-91-6 The title of the article was Palladium-Catalyzed Serendipitous Synthesis of Arylglyoxylic Amides from Arylglyoxylates and N,N-Dialkylamides in the Presence of Halopyridines. And the article contained the following:

A palladium-catalyzed synthesis of arylglyoxylic amides by the reaction of arylglyoxylates and N,N-dialkylamides in the presence of a 2,3-dihalopyridine has been realized for the first time. An anticipated 2,3-diaroylpyridine did not form in this reaction. The current study unveils an unprecedented role of 2,3-dihalopyridine toward this amidation. Our mechanistic study reveals that the arylglyoxylate could react with halopyridine to form a traceless activated pyridyl ester of arylglyoxylic acid, which upon subsequent reaction with amino surrogate, N,N-dialkylamides could form the arylglyoxylic amides. The experimental process involved the reaction of N,N-Diethylacetamide(cas: 685-91-6).Recommanded Product: 685-91-6

On December 4, 2020, Lv, Ningning; Yu, Shuling; Hong, Chao; Han, De-Man; Zhang, Yuhong published an article.Quality Control of N,N-Diethylacetamide The title of the article was Selectively Oxidative C(sp2)-H/C(sp3)-H Cross-Coupling of Benzamides with Amides by Nickel Catalysis. And the article contained the following:

The oxidative cross-coupling between the α-C(sp3)-H bond of amide in DMAc and the inert ortho-C(sp2)-H bond of benzamides is achieved for the first time by nickel catalysis, with the assistance of 8-aminoquinolyl group in the presence of a silver oxidant. Notably, the selectivity of conversion can be perfectly controlled by modulating the oxidant additives, and the products from the coupling of the C(sp3)-H bond adjacent to nitrogen of amides with benzamides are approached through the use of peroxide. The experimental process involved the reaction of N,N-Diethylacetamide(cas: 685-91-6).Quality Control of N,N-Diethylacetamide

Moglie, Yanina; Buxaderas, Eduardo; Mancini, Agustina; Alonso, Francisco; Radivoy, Gabriel published an article in 2019, the title of the article was Amide Bond Formation Catalyzed by Recyclable Copper Nanoparticles Supported on Zeolite Y under Mild Conditions.Application In Synthesis of N,N-Diethylacetamide And the article contains the following content:

A series of catalysts based on supported copper nanoparticles were prepared and tested in the amide bond formation from tertiary amines and acid anhydrides, in the presence of tert-Bu hydroperoxide as an oxidant. Copper nanoparticles on zeolite Y (CuNPs/ZY) was found to be the most efficient catalyst for the synthesis of amides, working in acetonitrile as solvent, under ligand- and base-free conditions in air. The products were obtained in good to excellent yields and in short reaction times. The CuNPs/ZY system also exhibited higher catalytic activity than some com. available copper and iron sources and it was reused in ten reaction cycles without any further pre-treatment. This methodol. was successfully scaled-up to a gram scale with no detriment to the yield. The experimental process involved the reaction of N,N-Diethylacetamide(cas: 685-91-6).Application In Synthesis of N,N-Diethylacetamide
