Abstract

Defluorinative hydrolysis (or alcoholysis) of gem-difluoroolefins (1) easily prepared via the facile difluoromethylenation of carbonyl compounds afforded the carboxylic acids (or esters). The homologation method was applied to the synthesis of anti-inflammatory ibuprofen. Furthermore, defluorinative hydrolysis of monofluoroolefins obtained via the reduction of 1 gave the aldehydes.
