Homogeneous RuCl2(PPh3)3-catalyzed regioselective liquid-phase transfer hydrogenation of carbon-carbon double bond in chlorobenzylidene ketones with ethylene glycol as hydrogen donor
The regioselective transfer hydrogenation of a carbon-carbon double bond of different chlorobenzylidene ketones is effectuated in ethylene glycol with a very high selectivity in the presence of homogeneous, tris(triphenylphosphine)ruthenium-(II) chloride
