Immobilized triazacyclononane derivatives as selective oxidation catalysts. Final technical report of DOE Award No. DE-FG02-99ER14968 with the University of Munich [Encapsulation of metal chelate and oxocatalysts in nanoporous hosts]

This project deals with the covalent anchoring of various derivatives of triazacyclononane (TACN)ligands in the channels of period mesoporous materials and the catalytic activity of the corresponding metal complexes. Catalyst preparation, ligand immobilization, catalyst characterization, and catalyst performance in selective oxidation are discussed. A wide range of pendant variations on the TACN ligand can be synthesized, and ligands can be covalently bound to high surface area, pseudo-crystall… more

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 mechanisti… more
