Selective synthesis of indenylruthenium(II) vinylvinylidene complexes via unstable allenylidene intermediates:Unexpected formation of alkenyl-phosphonio complexes(E)-[Ru{C(H)=C(PPh3)R}(η5-C9H7) (PPh3)2][PF6](R=1-cyclohexenyl,1-cycloheptenyl)through nucleophilic addition

The vinylvinylidene complexes [Ru{=C=C(H)C=CRCH2(CH2)nCH2}(η 5-C9H7)L2][PF6] (L = PPh3, L2 = 1,2-bis(diphenylphosphino)ethane (dppe); n = 1 (2a,b), 2 (3a,b), 3 (4a,b)) have been prepared by reaction of [RuCl(η5-C9H7)L2] with 1-ethynyl-1-cycloalkanols and NaPF6 in refluxing methanol. Deprotonation of the vinylidene derivatives with Al2O3 yields the neutral enynyl complexes [Ru{C≡CC=CHCH2(CH2)nCH 2}(η5-C9H7)L2] (5a,b, 6a,b, and 7a,b). The reaction of the enynyl complex [Ru(C≡CR)(η5-C9H7)(PPh 3)2] (R = 1-cyclohexenyl; 6a) with MeOSO2CF3 produces the disubstituted vinylvinylidene derivative [Ru{=C=C(Me)R}-(η5-C9H7)(PPh 3)2][CF3SO3] (R = 1-cyclohexenyl; 8a). The crystal structure of 8a was determined by X-ray diffraction methods. In the structure the Ru=C=C chain is nearly linear (Ru-C(1)-C(2) = 176.2(4)°) with an Ru-C(1) distance of 1.838(5) A?. The indenyl ligand is η5-bonded to the metal with the benzo ring orientated trans with respect to the vinylidene group. When the reaction of [RuCl(η5-C9H7)(PPh3) 2] with 1-ethynylcyclohexanol or 1-ethynylcyclopentanol and NaPF6 takes place in the presence of PPh3, the alkynyl-phosphonio complexes [Ru{C≡CC(PPh3)CH2CH2(CH 2)nCH2}(η5-C9H 7)(PPh3)2][PF6] (n = 1 (11a), 2 (12a)) were obtained via nucleophilic attack of the PPh3 on Cγ of the unstable allenylidene complexes [Ru{=C=C=CCH2CH2(CH2)nCH 2}(η5-C9H7)(PPh 3)2][PF6] (n = 1 (9a), 2 (10a)). The vinylvinylidene complexes 3a (n = 2) and 4a (n = 3) also react with PPh3, giving the alkenyl-phosphonio complexes (E)-[Ru{C(H)=C(PPh3)C=CHCH2(CH2) nCH2}(η5-C9H 7)(PPh3)2][PF6] (n = 2 (13a), 3 (14a)). The structure of 13a was confirmed by X-ray diffraction methods. A possible mechanism for the formation of 13a and 14a is proposed.
