Abstract

Abstract : A tandem process of multiple C–H activation, intermolecular highly meta -selective C–H amination, and intramolecular C–H amination between amidines and alkynes has been developed. Abstract : A tandem process of multiple C–H activation and intermolecular highly meta -selective C–H amination between amidines and alkynes has been developed. Mechanistic studies demonstrate that the reaction is proposed to proceed through two different Rh(i )–Rh(iii ) catalytic cycles, wherein Rhodium-complex I and Rhodacycle intermediate II were isolated for the first time.
