The esters 1 of N-hydroxy-2-thiopyridone react smoothly at room temperature in a thermal reaction with diethyl azo-dicarboxylic ester to furnish adducts 2 of a novel structure.Photolysis of these adducts affords a convenient route to the little known tetrazanes 8.Azo compounds without electron withdrawing groups do not react.The Cookson reagent, however, is so reactive that it gives diacyl derivatives of type 14.
