Abstract

Reactions of (E)-[(2-aroyl)ethenyl]triphenylphosphonium bromides with hydroxylamine hydrochloride resulted in the formation of oximes undergoing α-phenyl migration when reacted with aqueous alkali. Reaction of these salts with hydrazine hydrochloride and o-phenylenediamine yielded [(2-aroyl)ethyl]triphenyl-phosphonium salts and phosphorus-substituted quinoxalines, respectively.
