Pb(OAc)4(CH3)3SiN3 reacts with simple nucleophilic olefins to form mostly diazides and azide-acetoxy compounds,2 while with steroidal olefines α-azidosteroidketones3 are afforded. Contrary to this result the title reagent reacts not only with nucleophilic but also with electrophilic double-bounds yielding α-azido-carbonyl compounds. Not any azide-acetoxy compound is formed. Compound 14 indicates that

叠氮化物和
叠氮化乙酰氧基的化合物,2,同时用甾族烯烃α-azidosteroidketones 3被提供。与该结果相反,标题试剂不仅与亲核试剂反应,而且还与亲电双键反应,生成α-
叠氮基-羰基化合物。没有形成任何
叠氮化物-乙酰氧基化合物。化合物14表明通过芳基的活化对于该反应不是必需的。这种反应的极性机制似乎是不可能的。
