Organosilicon compounds play an important role as reagents and intermediates in organic synthesis, and as monomers for the production of oligomers, polymers and composites used in various applications. Thus, new catalytic transformations are highly desired, and there is considerable interest in development of more cost-effective and selective hydrosilylation catalysts. Currently, platinum is the primary metal used for such catalysis, but its rising cost motivates research into use of alternative catalysts based on more abundant metals. A general approach to addressing these issues involves discovery of new fundamental reaction steps for activations of appropriate substrates. This presentation will focus on transition metal complexes that enable new mechanisms for transformations of organosilanes, including hydrosilylation. Such complexes include unsaturated metal silylene complexes, sigma-complexes of cationic metal centers, and coordinatively unsaturated, first-row transition metal complexes.
