H2 cleavage, hydride formation, and catalytic hydrogenation of imines with zinc complexes of C5Me5 and N-heterocyclic carbenes
Jochmann, Phillip,Stephan, Douglas W.
, p. 9831 - 9835 (2013)
Decamethylzincocene, [ZnCp2], reacts with H2 to give the reduced ZnI compound [Zn2Cp2]. In the presence of coordinating and (more efficiently) of non-coordinating N-heterocyclic carbenes (NHCs), the catalytic hydrogenation of imines with H2 is achieved. The monomeric hydride [Zn(Cp)(H)(SIMes)] is presented and its mechanistic implications are considered. Copyright
Zirconium-Catalyzed Imine Hydrogenation via a Frustrated Lewis Pair Mechanism
Flynn, Stephanie R.,Metters, Owen J.,Manners, Ian,Wass, Duncan F.
, p. 847 - 850 (2016)
Zirconium-based frustrated Lewis pairs (FLPs) are active imine hydrogenation catalysts under mild conditions. Complexes of the type [CpR2ZrOMes][B(C6F5)4] utilize the imine substrate itself as the Lewis base component of the FLP. Catalyst performance is a function of ligand structure; in general more bulky, more electron rich cyclopentadienyl derivatives give the best results. However, Cp? derivatives are not catalytically active, being stable after initial heterolytic cleavage of H2; this allows experimental verification of the competence of the zirconocene-imine pair in FLP-type heterolytic H2 cleavage. Enamines and protected nitriles are also hydrogenated if an additional internal phosphine base is used.

Despite a myriad of available pharmacotherapies for the treatment of type 2 diabetes (T2D), challenges still exist in achieving glycemic control. Several novel glucose-lowering strategies are currently under clinical investigation, highlighting the need f
Imine hydrogenation by alkylaluminum catalysts
Hatnean, Jillian A.,Thomson, Jordan W.,Chase, Preston A.,Stephan, Douglas W.
supporting information, p. 301 - 303 (2014/01/06)
Di-isobutylaluminum hydride and tri-iso-butylaluminum (DIBAL 1, TIBAL 2) are shown to be efficient hydrogenation catalysts for a variety of imines at 100 °C and 100 atm of H2, operating via a hydroalumination/ hydrogenolysis mechanism.
