REACTION DE PERHALOSTYRENES AVEC LES ORGANOLITHIENS. PREPARATION D'ARYL-1 ALCYNES-1 RAMIFIES PAR L'INTERMEDIAIRE D'ARYL FLUORO ACETYLENES

Article abstract of DOI:10.1016/S0040-4039(00)85592-6

Organolithium compounds react with 1-aryl 2-chloro 1,2-difluoroethylene to give derivatives of type Ar-C*C-R'.Hydrolysis of the intermediate carbanionic species yilds the corresponding α,β-difluorostyrenes.
