A novelthree-component coupling between trimethylsilylmethylphosphonate, acyl fluoride, and aldehyde has been developed. A sequential nucleophilic addition of lithio-trimethylsilylmethylphosphonate to the acyl fluoride and Horner–Wadsworth–Emmons reaction of an aldehyde with the lithio-β-ketophosphonate generated in situ by desilylation at the α-position of the α-silyl-β-ketophosphonate by fluoride
practical nickel-catalyzed deaminative alkylation of Katritzky salts with cyclopropyl alcohols via merging C–N and C–C bond activation. This protocol enables the formation of an alkyl–alkyl bond along with the generation of a versatile ketone functional group in a single operation, thus providing a convenient approach for accessing β-alkyl ketones. This reaction is distinguished by its high functional
