Abstract

Abstract Results obtained and observations made by applying the title method for the synthesis of enaminones 5a-o, using triphenylphosphine as a thiophile and triethylamine as a base, are reported. The product distributions of the deprotonations of α-phenacylthio iminium bromides with and without thiophile and those known from thiouronium and heterocyclic thionium analogs are compared.
