Treatment of the starting complexes [(η6-C6Me6)Ru(P～O)X2] (X = Cl (1), CH3 (2); P～O = η1 (P)-coordinated ether-phosphine ligand Ph2PCH2CH2OCH3) with NaBPh4 and HBF4, respectively, lead to the chelated complexes [(η6-C6Me6)Ru(P∩O)X][BR 4] (X = Cl (3a), CH3 (3b); R = Ph (3a), F (3b); P∩O = η2 (O,P)-coordinated ligand). The rupture of the Ru-O bond in 3a,b with carbon monoxide and acetonitrile results in the formation of the corresponding complexes [(η6-C6Me6)Ru(CO)(P～O)X][BR 4] (4a,b) and [(η6-C6Me6)Ru(CH3CN)(P～O)X] [BR4] (5a,b). The structure of 4a was determined by single-crystal X-ray diffraction. In a similar way the cleavage of the Ru-O bond is achieved when 3a is reacted with tert-butyl isocyanide and 3b with ethene to give the adducts [(η6-C6Me6)Ru(CN tBu)(P～O)Cl][BPh4] (6a) and [(η6-C6Me6)Ru(η2-C 2H4)(CH3)(P～O)][BF4] (7b). All compounds are obtained in excellent yields and under mild conditions.
