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- and 7-methylisoquinolines 3 and 4.On the other hand reactions of 3-methylbenzyne with the triazines 1d and 1e proceeded with high regioselectivity, giving only the 5-methylisoquinoline 5a and the 8-methylisoquinoline 6b, respectively.

Arene formation by catalytic transfer hydrogenolysis of aryloxytetrazolyl ethers in the liquid-phase shows biphasic concentration-time curves which indicate rate-limiting dissociation of heterogeneous complexes between catalyst and one of the reaction products, a tetrazolone.A dependence of catalytic reaction rate on pH and following modifications made to the catalyst are reported also.
