Abstract

Treatment of o-carborane with n-butyllithium, sulfur and CpCo(CO)I2 in CH2Cl2 at room temperature gives the half-sandwich 16e carborane complex CpCo[S2C2B10H10], which reacts with PPh2Me, PPhMe2, PMe3 to afford addition products CpCo[S2C2B10H10]PPh2Me (I), CpCo[S2C2B10H10]PPhMe2 (II), CpCo[S2C2B10H10]PMe3(III), respectively. I, II and III have been characterized by IR, 1H NMR, 13C NMR, 11B NMR, elemental analysis, mass spectrum and single-crystal X-ray diffraction analysis (CIF files CCDC nos. 2394909 (I), 2394910 (II), and 2394908 (III)).
