Abstract
This mini review focuses on the recent advances in catalytic intermolecular hydroaminations : Pd-, Ni-, Rh-, and Ru-catalyzed addition reactions of amine to olefins, and their mechanistic insights are described concisely. Oxidative addition of ammonia to an Ir complex to activate the N-H bond is mentioned as well, that is a milestone achievement toward the intermolecular hydroamination using ammonia as a nitrogen source.
