Iodine-Catalyzed Aminosulfonation of Hydrocarbons by Imidoiodinanes. a Synthetic and Mechanistic Investigation

[摘要]：The amino-functionalization of a range of benzylic and some aliphatic saturated and unsaturated hydrocarbons by reaction with imido-iodinanes (PhI=NSO2Ar) is catalyzed by I-2 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, and stereoselectivity tests, are indicative of a stepwise pathway in C-N bond formation Investigation into the nature of the active aminating species has led to the isolation of a novel aminating agent formulated as (ArSO2N),I-y (x = 1, y = 2, or x = 3, y = 4)
