Bis(phosphine)ruthenium derivatives (η5-C5Me5)RuCl(PR3=PMe3, PMe2Ph, PEt3, PMePh2, 1/2DPPE, 1/2DPPB) (2a∼2f) have been synthesized by the reaction of [(η5-C5Me5)RuCl2]2 (1) with excessive phosphine in ethanol. The reaction of complexes (η5-C5Me5)Ru(PR3)2Cl with NaBH4 in ethanol gave the corresponding hydride complexes (η5-C5Me5)Ru(PR3)2H (PR3=PMe3, PEt3, PMePh2, 1/2 DPPE, 1/2DPPB) (3a∼3e). Chloride complexes (2a∼2f) and hydride complexes (3a∼3e) were isolated as crystals, which were characterized by IR, 1H-NMR, and elemental analysis.
