The PCP pincer complex, IrH2(C6H3-2,6-(CH2PBut2)2) catalyzes the transfer dehydrogenation of secondary amines to imines. The catalytic system is highly sensitive to both steric and electronic factors and greater than 99% regioselectivity are observed

Values for the ∆H ‡ of dehydrogenation NaAlH4 to Na3AlH6/Al and Na3AlH6 to NaH/Al and the reverse hydrogenation reactions have been determined through kinetic studies of 2 mol % Ti and Zr doped hydride. We find that the experimentally determined
