Manganese (III) catalyzed C—H aminations

Reactions that directly install nitrogen into CH bonds of complex molecules are significant because of their potential to change the chemical and biological properties of a given compound. Selective intramolecular CH amination reactions that achieve high levels of reactivity, while maintaining excellent site-selectivity and functional-group tolerance is a challenging problem. Herein is reported a manganese perchlorophthalocyanine catalyst [Mn.sup.III(ClPc)] for intermolecular benzylic CH amination of bioactive molecules and natural products that proceeds with unprecedented levels of reactivity and site-selectivity. In the presence of Brnsted or Lewis acid, the [Mn.sup.III(ClPc)]-catalyzed CH amination demonstrates unique tolerance for tertiary amine, pyridine and benzimidazole functionalities. Mechanistic studies indicate that CH amination proceeds through an electrophilic metallonitrene intermediate via a stepwise pathway where CH cleavage is the rate-determining step of the reaction. Collectively these mechanistic features contrast previous base-metal catalyzed CH aminations. The catalyst can be a compound of Formula I: ##STR00001##
