Abstract

Extremely facile metal insertion into strong chemical bonds that are normally inert can take place in pincer systems, resulting in unequivocal demonstration and mechanistic evaluation of metal insertion into unstrained C-C and C-O bonds in a solution. This chapter presents an overview of intramolecular C-C and C-O bond activation in pincer systems. C-H and O-H bond activation processes that occur concurrently with C-C and C-O cleavages in most of the studied pincer complexes are discussed in the chapter. PCX-metal systems prove to be excellent models for strong bond activation studies. They provide mechanistic insight into the activation of strong C-C bonds. In most PCX-metal systems, C-C oxidative addition is thermodynamically more favorable than other competing C-H activation processes. C-C activation can proceed directly and does not require prior C-H activation.
