Carbodiimide (R1-N=C=N-R2) is a novel organic synthon with a special azaalne structure and electronic properties. Therefore, it exhibits novel and rich reaction characteristics. It was previously reported that the two active sites of carbodiimide are the central carbon atom and the C=N double bond. Professor Zhang Wenxiong’s research group from Peking University discovered the selective cleavage and recombination of C=N double bonds and C(sp3)-H bonds in carbodiimide molecules [1][1]
