Sequential arene coordination and C–F insertion in the reactions of (η5-pentamethylcyclopentadienyl)rhodium complexes with hexafluorobenzene

Abstract

Hexafluorobenzene reacts with [(η⁵-C₅Me₅)Rh(PMe₃)(C₂H₄)] in two sequential photochemical reactions to yield first the arene coordination product, [(η⁵-C₅Me₅)Rh(PMe₃)(η²-C₆F₆)], and then the C–F insertion product, [(η-⁵-C₅Me₅)Rh(PMe₃)(C₆F₅)F]; chlorination of the latter generates [(η⁵-C₅Me₅)Rh(PMe₃)(C₆F₅)Cl], the structure of which has been determined crystallographically.
