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 alpha-phenacylthio iminium bromides with and without thiophile and those known from thiouronium and heterocyclic thionium analogs are compared.

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 alpha-phenacylthio iminium bromides with and without thiophile and those known from thiouronium and heterocyclic thionium analogs are compared.File in questo prodotto:
