A challenging metal-free azide insertion of α-aryl α-diazoesters in the presence of B(C6F5)3 (5 mol %) was developed for the first time. The reaction features an easy operation, wide substrate scope, and mild conditions and affords the corresponding products in moderate to high yields. More importantly, alkene and alkyne functional groups were well tolerated because no cyclopropanation or cyclopropenation
首次开发了在B(C 6 F 5)3(5 mol%)存在下具有挑战性的无金属的α-芳基α-重氮酸酯叠氮化物插入物。该反应具有易于操作,底物范围宽和条件温和的特点,并以中等至高收率提供了相应的产物。更重要的是,由于未观察到环丙烷化或环丙烷化,因此对烯烃和炔烃官能团的耐受性良好。此外,在简单转化后,相应的叠氮化物产物可以转化为伯胺或1,2,3-三唑衍生物。
