Base-induced generation of aryl(1,2,3-triazol-1-yl) carbenes from 1-[(N-phenylsulfonyl)benzohydrazonoyl]-1,2,3-triazoles and their ring enlargement to 3-aryl-1,2,4-triazines

The Bamford-Stevens reactions of 1-[N-(phenylsulfonyl)-benzohydrazonoyl]-1,2,3-triazole derivatives, readily available from the 1,3-dipolar cycloadditions of N-(phenylsulfonyl)benzohydrazonoyl azides with enamines, were examined and the transformation fro

Synthesis of 1,2,4-triazines. XII. New synthesis of 1,2,4-triazines with a functional group in the 6-position

6-Acyl- (15, 17) and 6-ethoxycarbonyl-5-substituted 1,2,4-triazines (11) were prepared by refluxing acylhydrazones (10, 14) or N,N-dimethylaminomethylenehydrazones (16) with ammonium acetate in acetic acid. NMR-studies confirmed the high regio selectivity
