Abstract

Reaction of [Mo(CO)₃(η⁷-C₇H₇)]BF₄ with arenes gives [Mo(η⁷-C₇H₇)(η⁶-arene)]BF₄, whereas the halides Me₃SiX (X = Cl, Br, or I) form [Mo₂X₃(η⁷-C₇H₇)₂], the latter being reversibly oxidised to binuclear monocations; treatment of the mononuclear cations with acacH affords [Mo(acac)(H₂O)(η⁷-C₇H₇)]⁺, which with anions (X^–) yields the neutral species [MoX(acac)(η⁷-C₇H₇)], both these paramagnetic complexes being structurally characterised by X-ray crystallography.
