Abstract

Abstract : Efficient catalytic formic acid dehydrogenation was achieved with Ru(ii ) complexes of meso -tetraphos-1 under batch and continuous feed conditions. Abstract : Well-defined and in situ made Ru(ii ) complexes of the linear tetraphosphine ligand meso -1, 1, 4, 7, 10, 10-hexaphenyl-1, 4, 7, 10-tetraphosphadecane (tetraphos-1, P4) proved to be effective catalysts for selective formic acid dehydrogenation with good yields and TONs in the presence of an added amine, both under batch and continuous feed experimental conditions. The mechanism was studied by solution NMR and DFT calculations, highlighting the role of the trans -dihydrido complex [Ru(H)2 ( meso -P4)] as the active species in catalysis.
