Abstract
Improved catalytic methods are disclosed. The methods include both hydrogenation and disproportionation catalysis. While the reaction conditions for hydrogenation and disproportionation differ, the catalysts disclosed herein can be used for either process. In certain aspects, the methods utilize a catalyst: CpM(N—N)Ln; wherein Cp is a substituted or unsubstituted cyclopentadienyl ligand; wherein M is selected from the group consisting of Ir and Rh; wherein N—N is a substituted or unsubstituted bidentate ligand selected from the group consisting of a bipyridine ligand and a phenanthroline ligand; wherein n is 0 or 1; and wherein when n is 1 L is selected from the group consisting of an anion and a molecule of a solvent.
