Abstract

A study of the decomposition of 1-(2'-carboxyphenyl)-3, 3-dimethyltriazene and the tetrabromoand tetrachloro-analogues showed that the arenediazonium-2-carboxylates were intermediates in the formation of the corresponding arynes: the 1-(2'-carboxyteirahalophenyl )-3, 3-dimethyltriazenes are stable precursors that enable cycloaddition reactions of the tetrahalobenzynes to be carried out in acceptable yields using substrates such as N- ...
