Abstract

Benzyne has been generated from benzenediazonium-2-carboxylate in the presence of several 1, 2, 4-triazines 1 and isoquinolines 2 have been isolated in moderate yield. 1- Aminobenzotriazole was also used as the source of benzyne and isoquinolines were again isolated in moderate yield from these reactions. 4-Methylbenzyne, which was generated from 5-methylanthranilic acid, reacted unselectively with the triazines to give mixtures of 6- ...
