Synthesis, Characterization, and Behavior of Hydridoruthenium Carbonyl Clusters Substituted with Functionalized Phosphines in the Presence of Hydrogen. 1. H4Ru4(CO)8[P(CH2OCOR)3]4 (R = CH3−, C2H5−, (CH3)2CH−, (CH3)3C−, (S)-C2H5CH(CH3)−)

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.
