complex of general formula Cl2Ru(Ph2PCH2CH2OCH3)2(C4H10N2) 2 was made available in good yield through treating
equimolar amounts of O)2 complex 1 with piperazine as
co-ligand. The hemilability ring open reaction of ether-phosphine inÇCl2Ru(Pcomplex 1 to
prepare complex 2 was monitored by 31P-NMR. The structure of complex 2 was
confirmed by elemental analysis, IR, 31P-NMR
1H-NMR,13C-NMR, FAB-MS and UV-visible spectroscopy.
