Copper-Catalyzed Reaction of Trifluoromethylketones with Aldehydes via a Copper Difluoroenolate
Doi, Ryohei,Ohashi, Masato,Ogoshi, Sensuke
, p. 341 - 344 (2016)
A copper-catalyzed reaction of easily accessible α,α,α-trifluoromethylketones with various aldehydes affords difluoro-methylene compounds in the presence of diboron and NaOtBu. The key process of the reaction is the formation of a copper difluoroenolate by 1,2-addition of a borylcopper intermediate to α,α,α-trifluoromethylketones and subsequent β-fluoride elimination. Mechanistic studies including the isolation and characterization of a possible anionic copper alkoxide intermediate are also described.
Copper-catalysed difluoroalkylation of aromatic aldehydes via a decarboxylation/aldol reaction

, p. 7654 - 7659 (2017/09/27)
A copper-catalysed tandem decarboxylation/aldol reaction of simple aromatic aldehydes with 2,2-difluoro-3-oxo-3-arylpropanoic acid has been developed under mild conditions. This method provides a new route for the direct one-pot synthesis of difluorinated aldols in moderate to good yields from simple substrates.
Metal-mediated Reformatsky reaction of bromodifluoromethyl ketone and aldehyde using water as solvent

, p. 45 - 50 (2013/10/21)
Water is demonstrated as a suitable solvent for an efficient and environmentally friendly method for the synthesis of α,α- difluorinated β-hydroxy carbonyl compounds through the Reformatsky reaction of bromodifluoromethyl ketones with aldehydes in the pre
