In this lecture, mechanistic studies of several catalytic C-H bond activation reactions will be discussed.1,2 (1)  Mechanistic understanding has been developed for direct distal meta-C-H bond (more than ten bonds away) activation in tethered arene containing a remote nitrile. A dimeric Pd-Ag complex as active catalyst has been proposed.3 (2) A novel mechanism has been proposed to understand the effect of  mono-protected amino acid as a ligand to promote the reactivity, regioselectivity,4 and stereoselectivity of Pd-catalyzed C-H bond activations.5 (3) The mechanism can be extended to understand the Pd-catalyzed viny-vinyl coupling reactions.6
