Group 13 Mixed Halide-Hydride and Rare Earth Complexes - New Selective Chiral Hydridic or Low Valent Reducing Agents

The principle objective of this project is to generate stereochemically discrete reductive environments about group 13 and low valent rare earth elements. These will be employed in a survey of asymmetric reduction in order to identify unique transformations. For group 13 elements; enantiospecific M-H bond environments will be invoked using either chiral N-heterocyclic carbenes or chiral amidinate ligands. For low valent rare earth species; enantiospecific anionic ligands will be applied to render selective one-electron transfer reagents. The application of gallium hydrides to a new Ga(III) redox-transmetallation synthesis of rare earth species will also be undertaken. Worldwide, this chemistry is remarkably underdeveloped.
