Ab initio electronic structure calculations using RHF, MP2, and CCSD(T) levels of theory have been used to investigate a reaction path for the hydrosilation reaction catalyzed by divalent titanium (modeled by TiH2 and TiCl2). Optimized structures and energies are presented. All levels of theory predict a barrierless reaction path compared to a barrier of at least 55 kcal/mol at the MP2 level for the analogous uncatalyzed reactions. The use of correlated methods (MP2 or CCSD(T)) is required to obtain accurate structures and energies.
