v-Triazolines. Part 8. 1-Aryl-4-alkyl- and -aryl-thiomethyl-5-amino-v-triazolines: synthesis and reactions with bases

Abstract

A series of 1-aryl-4-alkyl- and -aryl-thiomethyl-5-amino-v-triazolines has been synthesized and characterized. On reaction with bases they underwent amine and/or thiol elimination yielding 1-aryl-4-alkyl- or -aryl-thiomethyl-v-triazoles (2) and 1-aryl-4-methyl-5-amino-v-triazoles (3), respectively. These latter compounds were formed through aromatization of the 4-methylene-v-triazolines (6) arising primarily from the adducts (1) by thiolate elimination.
