摘要：One of the most straightforward pathways to synthesis desirable organic molecules is, in principle, the C-H bond functionalization. Stimulated by this perspective, tremendous effort has been devoted to the scission of C-H bonds in the past decades, involving transition metal catalysis and harsh condition applications. However, the selective aromatic C-H activation has still been considered as one of the most challenging topics in organic chemistry, not only due to the relative large bonding energy of the C-H bonds, but also due to the poor selectivity since multiple reaction sites exist.

Recently, the development of “on-surface chemistry”, in which heterogeneous catalysis has been performed on a metal support, provides alternative routes for the C-H functionalization. Herein, I will introduce our recent work relevant to the C-H activation on surface. The reaction pathway and the reaction barrier were revealed by STM observations and DFT calculations. In addition a surface controlled novel mono- and di-selectivity of the ortho C-H activation was reported.
