Popis:	The synthesis and characterization of phosphines containing ester groups P(CH2OCOR)3 (R = CH3−, C2H5−, (CH3)2CH−, (CH3)3C−, (S)-C2H5CH(CH3)−) are reported. The new hydridoruthenium complexes H4Ru4(CO)8[P(CH2OCOR)3]4 (R = CH3−, C2H5−, (CH3)2CH−, (CH3)3C−, (S)-C2H5CH(CH3)−) were synthesized and characterized. The structure of (+)-(S)-H4Ru4(CO)8{P[CH2OCOCH(CH3)C2H5]3}4 was determined by X-ray diffraction. The behavior of these complexes in hydrocarbon solution with hydrogen under pressure (130 atm) in the temperature range 25−130 °C has been investigated. The ester groups present in the ligand P(CH2OCOR)3 are hydrogenated under mild conditions with formation of the corresponding alcohol RCH2OH.
