Electrochimie de composés organométalliques. I. Electrosynthèse de cyclopentadiène cyclopentadiényl cobalt substitués

Abstract

Cobaltocene anions have been prepared electrochemically in dimethylformamide. Their reaction with various electrophiles gives, in quantitative yields, substituted cyclopentadiene cobalt cyclopentadienyls, some of which cannot be prepared by usual methods.Substituted cyclopentadiene cobalt cyclopentadienyls are also obtained in excellent yield, by reaction of electrochemically generated cobaltocene with organic halides.
