Transfer hydrogenation of ketones and activated olefins using chelating NHC ruthenium complexes

Horn, Sabine ; Gandolfi, Claudio ; Albrecht, Martin

In: European Journal of Inorganic Chemistry, 2011, vol. 2011, no. 18, p. 2863–2868

N-Heterocyclic carbene (NHC) ruthenium complexes consisting of different donor substituents attached to the NHC ligand efficiently catalyse the transfer hydrogenation of ketones and of activated olefins in α,β-unsaturated ketones to give saturated alcohols. The most active catalyst precursor contains a tethered olefin as a hemilabile donor site. This complex also converts nitriles and,...

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 =...

Govindaswamy, Padavattan ; Canivet, Jérôme ; Therrien, Bruno ; Süss-Fink, Georg ; Štěpnička, Petr ; Ludvík, Jiří

In: Journal of Organometallic Chemistry, 2007, vol. 692, no. 17, p. 3664-3675

The mononuclear cations [(η5-C5Me5)RhCl(bpym)]+ (1), [(η5-C5Me5)IrCl(bpym)]+ (2), [(η6-p-PriC6H4Me)RuCl(bpym)]+ (3) and [(η6-C6Me6)RuCl(bpym)]+ (4) as well as the dinuclear dications...

Water-Soluble Arene Ruthenium Complexes Containing a trans-1,2-Diaminocyclohexane Ligand as Enantioselective Transfer Hydrogenation Catalysts in Aqueous Solution

Canivet, Jérôme ; Labat, Gael ; Stoeckli-Evans, Helen ; Süss-Fink, Georg

In: European Journal of Inorganic Chemistry, 2005, vol. 22, p. 4493 - 4500

The cationic chloro complexes [(arene)Ru(H2N∩NH2)Cl]+ (1: arene = C6H6; 2: arene = p-MeC6H4iPr; 3: arene = C6Me6) have been synthesised from the corresponding arene ruthenium dichloride dimers and enantiopure (R,R or S,S)...
