Exploring Rhenium Arene Piano-Stool Chemistry with [Re(η⁶-C₆H₆)(NCCH₃)₃]⁺: A Powerful Semi-Solvated Precursor.

ABSTRACT: Thermal treatment of the Re^III hydride complex [ReH(η⁵-C₆H₇)(η⁶-C₆H₆)]⁺ in CH₃CN results in the formation of [Re(η⁶-C₆H₆)(NCCH₃)₃]⁺. This semi-solvated complex is remarkably stable under an ambient atmosphere and exhibits a fast CH₃CN self-exchange, which facilitates substitution reactions. The CH₃CN ligands are replaced by σ-donating phosphines such as trimethyl phosphine (PMe₃), triphenyl phosphine (PPh₃), or the bidentate 1,2-bis(diphenylphosphino)ethane (dppe) to afford [Re(η⁶-C₆H₆)(NCCH₃)_3-x(PR₃)_x
