Controlled potential electrolysis of triphenylphosphine in acetonitrile containing various primary alcohols and dialkyldisulfides resulted in the formation of the corresponding alkoxy and alkylthio triphenylphosphonium salts, [Ph3P+-X] [ClO4-]. Compounds with X=OMe, OEt, OPrn, SMe, SEt, and SPrn were isolated. The alkoxy derivatives reacted with imidazole and thiophenol under mild conditions to give the corresponding N- and S-alkylated products quantitatively.
