| Description |
The hexa-coordinated chelate complexes of the type [Ru(CO)2Cl2(P-P)](1a,b) [where P-P = 9,9-dimethyl-
4,5-bis(diphenylphosphino)xanthene(a) and [bis(2-diphenylphosphinophenyl)ether(b)] have been synthesized
by reacting the polymeric precursor [Ru(CO)2Cl2]n with the ligands in 1:1 molar ratio. The complexes
1a,b are characterized by elemental analyses, Mass, IR and NMR spectroscopy together with the
single crystal X-ray structure determination of 1a. The compound 1a crystallizes in a monoclinic system
with space group C2/c showing a slightly distorted octahedral geometry around the Ru centre. The complexes
1a and 1b are thermally stable up to 300 �C and exhibit high catalytic activity in transfer hydrogenation
of aldehyde and ketones to corresponding alcohols. The complexes 1a and 1b show much higher
catalytic activity for the hydrogenation of aldehyde than ketones. In general, the catalytic efficiency of 1b
is higher compared with 1a.
