of sulfides, sulfoxides, and olefins using 4H-1,2,4-triazole-4-amine as a nitrogen source with PhI(OAc)2 as an oxidant were achieved in moderate to high yields without the addition of a catalyst. The carbon–nitrogen and sulfur–nitrogen bond forming reactivity is consistent with a nitrene insertion mechanism in which the reactivity generally increases with decreasing N–H bond dissociation energy of the
使用 4H-1,2,4-三唑-4-胺作为氮源,PhI(OAc)2 作为氧化剂,在不添加催化剂的情况下以中等至高产率实现硫化物、亚砜和烯烃的亚胺化和酰胺化. 碳-氮和硫-氮键形成反应性与氮烯插入机制一致,其中反应性通常随着氮源 N-H 键解离能的降低和氧化剂氧化电位的增加而增加。
