The influence of phosphine cone angle on the synthesis and structures of [Rh(PR3)(Binor-S)]+ complexes that show C-C sigma interactions

Abstract:
Complexes that show C-C···Rh sigma interactions have been synthesized and characterised by NMR spectroscopy and X-ray diffraction: [Rh(PR3)(Binor-S)][BArF4], R = P tBu2Me, PCy2Ph; Ar = C6H 3(CF3)2, Binor-S = 1,2,4,5,6,8-dimetheno-S- indacene. These studies, in concert with previously published work, show that there is a rather narrow window of phosphine steric profile that supports the isolation of these interesting complexes, with the phosphine cone angle lying between 160° and 170°. © 2013 Elsevier B.V.
