Solvent and electrode stability is critical for the successful development of the rechargeable, organic electrolyte Li-O₂ (air) battery. Straight-chain alkyl amides, such as N,N-dimethylacetamide (DMA), show superior stability at the O₂ cathode compared to organic carbonates and glymes, but these solvents do not form a stable solid-electrolyte interphase (SEI) to prevent a sustained reaction with Li metal. In this work, we use electrochem. impedance spectroscopy and cycling tests on a sym. Li/electrolyte/Li cell to determine the ability of several fluorinated amide solvents to stabilize the lithium/electrolyte interface. The LiTFSI/N,N-dimethyltrifluoroacetamide (DMTFA) system shows the smallest interfacial impedance and the lowest polarization for Li dissolution and deposition. We present quantum chem. calculations indicating that α-fluorinated alkyl amides are reduced on Li to form insoluble LiF with no or little activation energy. XPS anal. confirms the presence of LiF in the SEI on Li metal exposed to DMTFA, which is likely to play an important role in stabilizing the lithium/electrolyte interface. The improved stability of a metallic Li anode in a rechargeable Li-O₂ battery with LiTFSI/DMA electrolyte is demonstrated using 2% DMTFA as the SEI-stabilizing additive.

All regioisomers of 3-aryl-3-trifluoromethyl-3H-diazirinyl sulfoxides and sulfones I (R = 2-, 3-, and 4-MeSOC₆H₄, -MeSO₂C₆H₄) were prepared in five steps from the corresponding bromothioanisoles in excellent overall yields. The key step involves a simultaneous oxidation of sulfide and diaziridine moieties resp., to yield either the diazirine sulfoxide or sulfone, depending on reaction conditions.

Saha, Sayantani published the artcileMild catalytic deoxygenation of amides promoted by thorium metallocene, Application of N,N-Diethyl-2,2,2-trifluoroacetamide, the publication is Dalton Transactions (2020), 49(36), 12835-12841, database is CAplus and MEDLINE.

The organoactinide-catalyzed (Cp*₂ThMe₂) hydroborated reduction of a wide range of tertiary, secondary, and primary amides to the corresponding amines/amine-borane adducts via deoxygenation of the amides is reported herein. The catalytic reactions proceed under mild conditions with low catalyst loading and pinacolborane (HBpin) concentration in a selective fashion. Cp*₂ThMe₂ is capable of efficiently catalyzing the gram-scale reaction without a drop in efficiency. The amine-borane adducts are successfully converted into free amine products in high conversions, which increases the usefulness of this catalytic system. A plausible mechanism is proposed based on detailed kinetics, stoichiometric, and deuterium labeling studies.

A number of amines were identified for the 1st time in grapes. These include MeNH₂ [74-89-5], EtNH₂ [75-04-7], Et₂NH [109-89-7], PrNH₂ [107-10-8], isobutylamine [78-81-9], α-amylamine [96-15-1], isoamylamine [107-85-7], pyrrolidine [123-75-1], and 2-phenethylamine [64-04-0]. The trifluoroacetamides of the isolated amines were separated on Carbowax 20M or SE54 fused silica capillary columns and identified by retention times and mass spectra. Two amines, di-Et and α-amyl, were identified in wine for the 1st time. Mass spectra of the pure trifluoroacetyl derivatives of these amines are given. In a recent review, P. Schreier (1979) compiled a list of the volatile amines found in wines. The volatile amines he summarized plus others detected in wines are given.
