An addition reaction of dinuclear [(η 6 ‐C 6 Me 6 )Ru(η 3, 1 ‐ exo‐syn ‐CH 2 CHCHCHO)] 2 (BF 4 ) 2 ( 1 ) with different Lewis bases in acetone results in the formation of mononuclear [(η 6 ‐C 6 Me 6 )Ru(η 3 ‐ exo‐syn ‐CH 2 CHCHCHO)(L)](BF 4 ) (L = PMe 3 , 2 ; PPh 3 , 3 ; PHPh 2 , 4 ; Ph 2 PEtPy, 6 ; CO, 7 ) and dinuclear [{(η 6 ‐C 6 Me 6 )Ru(η 3 ‐ exo‐syn ‐CH 2 CHCHCHO)} 2 (μ 2 ‐dppe)](BF 4 ) 2 ( 5 ). The addition of Ph 2 PCH 2 CH 2 PPh 2 to the dinuclear product 1 affords 5 which show a bridging phosphine between two ruthenium centers. A comparative study of the new cationic arene derivatives and the corresponding isoelectronic Cp*Ru(heteropentadienyl) is established. All compounds were characterized by IR spectroscopy, high resolution mass spectrometry, NMR spectroscopy and the crystal structures of 2 and 3 are also described.
