New reductive transition metal-catalyzed processes are described. These reactions incoporate H atoms from water through the action of tetrahydroxydiboron and related reagents. Methods described include semihydrogenations of alkynes, and the reduction of heteroatom-containing functional groups. We also describe how reaction selectivity can be controlled by the nature of the transition metal catalyst (homogeneous versus heterogeneous), and provide a rationalization for these observations.
