benzylic and some aliphatic saturated and unsaturated hydrocarbons by reaction with imido-iodinanes (PhI═NSO2Ar) is catalyzed by I2 under operationally simple and mild conditions. The first examples of 1,2-functionalization of unactivated C−H bonds using imido-iodinanes as aminating agents are reported. Mechanistic investigations, including Hammett analysis, kinetic isotope effects, a cyclopropane clock experiment
的范围和苄一些脂肪族饱和及不饱和烃通过与亚氨基- iodinanes(PhI═NSO反应的氨基官能化2 Ar)之由I催化2操作简单和温和的条件下。报道了使用亚氨基碘烷作为胺化剂的未活化CH键的1,2-官能化的第一个例子。包括哈米特分析,动力学同位素效应,环丙烷钟实验和立体选择性试验在内的机理研究表明,CN键形成过程中存在逐步的途径。对活性胺化物种的性质的研究已导致分离出一种新的胺化剂,其配方为(ArSO 2 N)x I y(x= 1,y = 2;或x = 3,y = 4)。
