Organometallic chemistry, dinuclear

Reviews have appeared of the photophysics of molybdenum complexes, primary and secondary processes in organometallic chemistry, flash photolysis of Pe(CO)5 and Cr(CO)g, dinuclear manganese carbonyl compounds, the photochemistry of metal complexes isolated in low temperature matrices, cluster complexes, diene complexes, photoproduction of coordinativeiy unsaturated species containing rhodium or iridium, and redox chemiluminescence of organometallic compounds.Synthetic and metal organic photochemistry in industry has also been reviewed. 

The dinuclear d3-d3 (RO)3M=M(OR)3 alkoxide system has provided a fertile inorganic redox active and coordinatively unsaturated template for the development of organometallic chemistry via substrate activation. Some of these interesting reactions are depicted in Scheme 10 and Eqs. 239, 241, and 242.

The two or three bis(chelate) ligands that are coordinated to the metal centre may in fact be equivalent, it is the actual geometry of the whole stmcture, resembling a three-bladed propeller, which determines the chiral character of the molecule. In the area of helical chirality, other types of chiral complexes have been described, in particular the two-bladed dinuclear acetylenic complexes (2.18)(BF4)2 which represent a rare example in organometallic chemistry (Figure 2.26). ... 

Abstract While the organometallic chemistry of Pd in its (0), (+11), and (+IV) oxidation states is well established, organometaUic Pd(lll) chemistry remains widely unexplored. Few characterized Pd(III) complexes are known, which has inhibited detailed study of tbe organometallic chemistry of Pd(III). hi this review, the potential roles of both mono- and dinuclear Pd(ni) complexes in organometallic chemistry are discussed. While not widely recognized, Pd in the (+111) oxidation state may play a significant role in a variety of known Pd-catalyzed reactions.
