The esters 1 of N-hydroxy-2-thiopyridone react smoothly at room temperature in a thermal reaction with diethyl azodicarboxylic 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
N-羟基-2-硫代吡啶酮的酯1在室温下与偶氮二乙基二羧酸二乙酯热反应中平稳反应,以提供新颖结构的加合物2。这些加合物的光解作用提供了通往鲜为人知的四氮杂八烷的便捷途径。没有吸电子基团的偶氮化合物不会发生反应。但是,Cookson试剂的反应性非常强,因此会生成14型的二酰基衍生物。
