Water-Soluble Phenanthroline Complexes of Rhodium, Iridium and Ruthenium for the Regeneration of NADH in the Enzymatic Reduction of Ketones

Canivet, Jérôme ; Süss-Fink, Georg ; Štěpnička, Petr

In: European Journal of Inorganic Chemistry, 2007, vol. 30, p. 4736 - 4742

The nicotinamide coenzyme NADH, consumed in enantioselective reduction of ketones catalysed by alcohol dehydrogenases, needs to be regenerated in order to maintain enzymatic activity. We therefore studied the catalytic potential of the cationic complexes [(η5-C5Me5)Rh(N∩N)Cl]+ (1: N∩N = 1,10-phenanthroline; 2: N∩N =...

Water-soluble arene ruthenium catalysts containing sulfonated diamine ligands for asymmetric transfer hydrogenation of α-aryl ketones and imines in aqueous solution

Canivet, Jérôme ; Süss-Fink, Georg

In: Green Chemistry, 2007, vol. 9, p. 391-397

A new family of nine cationic organometallic aqua complexes of the type [(arene)Ru(RSO2NNH2)(OH2)]+ (1–9), containing chiral N,N-chelating ligands, has been synthesised and isolated as the tetrafluoroborate salts, which are water-soluble and stable to hydrolysis. The enantiopure complexes 1–9 catalyse the transfer hydrogenation of...
