C-H activation reactions allow conversion of relatively inexpensive and abundant hydrocarbons into the more sophisticated value-added molecules . With the notion of step-economical and environmentally friendly synthesis, direct functionalization of C-H bonds is considered as a powerful strategy for the synthesis and derivatization of organic molecules . Homogeneous catalysis employing transition metal complexes has been widely accepted as one of the most efficient ways to perform C-H activation-based synthesis with high selectivity under relatively mild conditions . In particular, reactions involving palladium-catalyzed activation of sp 2 or sp 3 C-H bonds of arenes or alkanes have been extensively investigated due to their wide scope and functional group tolerance .
