Selective transformation of carbonyl ligands to organic molecules. Final report, November 15, 1992--November 14, 1995
The hydrosilation chemistry involving manganese acyl complexes (L)(CO){sub 4}MnC(O)R (L = CO, PPh{sub 3}; R = CH{sub 3}, Ph) as substrates and as precatalysts has been developed. Results of a kinetics study on the (CO){sub 5}Mn(p-toluoyl)-catalyzed SiH/SiD exchange between DSiMe{sub 2}Ph and HSiMe{sub 2}Et established that coordinatively unsaturated (CO){sub 4}MnSiR{sub 3}, the active catalyst, sequentially adds one substrate silane and then releases a product silane. Results of this mechanistic study afforded the working hypothesis for much of our current research: manganese acyl-hydrosilane mixtures generate unsaturated silyl complexes, which are active catalysts for the hydrosilation of a variety of substrates. These active catalysts, (CO){sub 4}MnSiR{sub 3}, also were generated through photolysis of (CO){sub 5}MnSiR{sub 3}.
