Аннотация:Interaction of [Ru(η-C6H6)Cl2]2 with indenyl- or fluorenyllithium in THF gives, together with cationic benzene complexes [Ru(η5-C9H7)(η-C6H6)]+ and [Ru(ν5-C 13H9)(η-C6H6)]+, the neutral cyclohexadienyl derivatives Ru(η5-C9H6-C9H7) and Ru(η5-C13H9)(η5-C6H6-C13H9), respectively. Interaction of the cyclohexadienyl complexes with Al2O3, Ph3C+, and CF3CO2H has been studied. Reaction of Ru(η5-C13H9)(η5-C6H7) with CF3CO2H in the presence of an arene yields cationic cyclohexadienylarene complexes: [Ru(η5-C13H9)(η6-arene)]+ (arene=C6H6 or 1,3,5-Me3C6H3).
