Effect of Charge Distribution on Selective Hydrogenation of Conjugated Enones Catalyzed by Iridium Complexes
Selective hydrogenation of enones catalyzed by iridium complexe
Selective hydrogenation of PhCH=CHCOMe to the unsaturated alcohol catalysed by [IrH3(PR3)3] (R = alkyl or aryl)
Selective hydrogenation of benzylideneacetone (PhCH=CHCOMe) catalysed by iridiumphosphine systems prepared in situ is reported. Depending on the steric properties of the phosphine employed and the P:lr ratio, different species are formed in solution, as evidenced by n.m.r. spectroscopy. [IrH5(PR3)2] (R = alkyl or aryl) is a catalyst for the hydrogenation of the carbon-carbon double bond, whereas [IrH3(PR3)3] catalyses the reduction of the carbonyl group with a selectivity up to 100%

Flexible scorpionates for transfer hydrogenation: the first example of their catalytic application
Rhodium and iridium complexes of flexible scorpionate ligands based on azaindole were synthesised in good yields. The complexes were characterised in solution and in the solid state. Structural characterisation revealed a B-H-metal interaction, which is retained in solution. Given the greater flexibility of the ligand and potential cooperative effect of boron, the complexes were tested for their activity in the transfer hydrogenation of ketones
