Abstract

Abstract N 3-Acylamidrazone ylides 3 were synthesized by the reaction of 2- (iminophenylmethyl)-1, 1, 1-trimethylhydrazinium hydroxide, inner salt (2a) or 2-(1- iminoethyl)-1, 1, 1-trimethylhydrazinium hydroxide, inner salt (2b) with acyl chlorides or acetic anhydride. Thermolysis of 3 gave 3, 5-disubstituted oxadiazoles 4 and trimethylamine.
