Thermal decomposition of vinyl azides (1a–c) gives isoquinolines (3), benzazepines (4), or aziridines (5) and (6) by preferential reaction at the unsaturated substituent; removal of this unsaturation as in the epoxides (1d,1e) leads exclusively to 4-substituted indoles.
叠氮化乙烯基(1a–c)的热分解通过不饱和取代基上的优先反应生成异喹啉(3),苯并ze庚因(4)或氮丙啶(5)和(6);如在环氧化物(1d,1e)中除去这种不饱和键仅会导致4-取代的吲哚。
