Abstract
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 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, 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)(x)I(y) (x = 1, y = 2; or x = 3, y = 4).
