Abstract

Addition of H2 to [Rh(iBu2PCH2CH2PiBu2)(NBD)][BArCl4] (NBD = norbornadiene, ArCl = 3,5-Cl2C6H3) in the solid-state results in the rapid formation of zwitterionic [Rh(iBu2PCH2CH2PiBu2){(η6-C6H3Cl2)BArCl3}] by a gas/solid reaction. This undergoes slow C–Cl bond cleavage in the solid-state to ultimately afford the dimeric Rh(III) complex [RhCl(iBu2PCH2CH2PiBu2){C6H3Cl(BArCl3)}]2. This reactivity is mirrored in solution (CH2Cl2). Kinetic data for the C–Cl activation in both the solid-state and solution are reported.
