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.

am和炔烃之间的铑催化的多重CH活化/高度亚选择性CH胺化。

多个C-H活化和分子间高度的串接处理的元脒和炔烃之间-选择性C-H的胺化得到了发展。机理研究表明，建议该反应通过两个不同的Rh（I）-Rh（III）催化循环进行，其中首次分离了铑配合物I和Rhodacycle中间体II。
