Abstract

Phenylacetylene reacts with dimethylammonium azide to give a mixture of 4-phenyl-1,2,3-triazole and 5-phenyltetrazole. Formation of 5-phenyltetrazole could be explained by 1,3-cycloaddition of azide to benzonitrile formed by decomposition of 4-phenyl-1,2,3-triazole.

Keywords

azidation; 4-phenyl-1,2,3-triazole; ring-expansion; 5-phenyltetrazole
