Abstract
This review focuses on a literature survey of the hydroarylation of alkynes via aryl C-H bond cleavage to prepare aryl-alkenes in the past thirty years. These efficient methods catalyzed by various metal complexes or protic acids are discussed respectively. Several reaction paths involved in these hydroarylations of alkynes are emphasized, which are aryl C-H activation by transition metals, formation of metal vinylidenes and Friedel-Crafts type process. In addition, some applications of these methods in organic synthesis are also introduced.

Catalytic C-H bond activation as a tool for functionalization of heterocycles
The major topic is the functionalization of heterocycles through catalyzed C-H bond activation. The strategies based on C-H activation not only provide straightforward formation of C-C or C-X bonds but, more importantly, allow for the avoidance of pre-functionalization of one or two of the cross-coupling partners. The beneficial impact of ...read more
