Replacing triethylamine by heterogeneous inorganic bases makes it possible to animate benzene or other nitrene acceptors, using the title reagent, previously reported to be scarcely reactive. Products of C-H insertion and/or those coming from intermediate aziridines are also obtained.
用异质无机碱代替三乙胺,可以使用以前报道的几乎没有反应性的标题试剂,使苯或其他氮烯受体发生动画化。还获得CH插入的产物和/或来自中间氮丙啶的产物。
