Hydrogenation accounts for over half the chiral compounds made by man not produced via physical or enzymatic resolution. This fact portends an equally powerful approach to reductive C-C bond formations mediated by hydrogen – catalytic couplings achieved simply through the exposure of two or more molecules to gaseous hydrogen in the presence of a metallic catalyst. Our laboratory is engaged in the first systematic efforts toward the development of hydrogen-mediated C-C couplings beyond alkene hydroformylation. These transformations add a new dimension to catalytic hydrogenation; one of chemistry's oldest and most broadly utilized processes.
