Cyclometalated phosphine-based pincer complexes: Mechanistic insight in catalysis, coordination, and bond activation

The combination of synthetic, structural, coordination, mechanistic, and catalytic studies employing series of newly synthesized PCX (X=P,N,O) ligands and metal complexes has provided much fundamental insight into the factors dominating the reactivity of these intriguing complexes. Thus, it has resulted in a far better understanding of how new reactive PCP-based complexes should be designed. Moreover, the isolation of frozen" model intermediates provided much needed mechanistic data not possible to acquire with other ligand systems."
