Transition metal catalyzed C-H Functionalization is one of the most important and challenging research fields in organic chemistry and has rapidly evolved in recent decades.Some recent achievements in the field include i) minimizing the pre-activation procedures of substrates,ii) reducing waste production,and iii) shortening synthetic steps by developing direct activations and straightforward transformations of C-H bonds.With the rapid developments in chemistry and the continuous support of the Chinese government,Chinese chemists have played important roles in this emerging field in the past two decades.To stimulate the continued success of Chinese chemists,this work provides an intensive account of the current status of this important field in mainland China.
