A chiral meso-ABC-corrolatochromium(V) complex.
A chiral metallocorrole complex, oxo[5-(4-bromophenyl)-10-(pentafluorophenyl)-15-(2-thianaphthyl)corrolato]chromium(V) (7), was prepared and serves as the first example of an ABC-metallocorrole; meso substituents are of different electron-withdrawing capacity. An adaptation of a multistep protocol (D. T. Gryko) was made, followed by an aerobic oxidation using Cr(CO)(6) (Z. Gross). The X-ray crystal structure reveals the two enantiomers of 7. Electron paramagnetic resonance spectroscopy (g(iso) = 1.99) and cyclic voltammetry of 7 provide comparative data to that of the A(3)[tris(pfp)cCr(V)O] complex.
