Abstract
Treatment of o-carborane, n-butyllithium, sulfur, and MeCpCo(CO)I2 under argon leads to twoMeCp-cobalt complexes MeCpCoS2C2B10H10 (I) and (MeCp)2Co2S2C2B10H10 (II). Complex I reacts with phenylacetylene or dimethyl acetylene dicarboxylate to afford B–H activitied complex (MeCpCoS2C2B10H9)(Ph–C–CH2) (III) and addition complex (MeCpCoS2C2B10H10)(MeO2C–C=C–CO2Me) (IV), respectively. Complex II reacts neither with phenylacetylene nor with dimethyl acetylene dicarboxylate. Complexes II–IV have been characterized by elemental analysis, mass, NMR spectroscopy, IR, and X-ray structural analyses (CIF files CCDC nos. 1045892 (II), 1045893 (III) and 1045894 (IV)).
