Halide abstraction from [(Ph3P)2Rh(μ-Cl)] 2 by the sodium salt of the weakly coordinating [BArf 4]- anion [Arf = C6H 3(CF3)2-3,5] in the presence of excess arene offers a convenient, high-yielding route to the half-sandwich cations [(arene)Rh(PPh3)2]+[BArf 4]- [arene = benzene (1), toluene (2)]. Crystalline samples of 1 and 2 are isomorphous [a = 13.1270(2), b = 15.3030(2), c = 17.5760(3) A, α = 74.620(1), β = 81.533(1), γ = 88.540(1)° for 1] and feature the arene ligand bound to the rhodium atom in η6 fashion.
