(Tetramethylcyclobutadiene) cobalt complexes with monoanionic carborane ligands [9-L-7,8-C2B9H10](-) (L = SMe2, NMe3 and py)

Original language description

nido-Carborane 9-NMe3-7,8-C2B9H11 (2c) was synthesized by CuSO4 oxidation of anion [7,8-C2B9H12](-) in the presence of [Me3NH](+) in aqueous ammonia. Improved procedures for the preparation of nido-carboranes 9-SMe2-7,8-R-2-7,8-C2B9H9 (2a: R = H; 2b: R =Me) and 9-py-7,8-C2B9H11 (2d) were developed. nido-Carborane monoanions [9-L-7,8-R-2-7,8-C2B9H8](-) (1a-1d), generated by deprotonation of 2a-2d by NaH, react with Cb*CO(CO)(2)I or [Cb*Co(MeCN)(3)](+) (Cb* = C4Me4) to give complexes Cb*Co(eta-9-L-7,8-R-2-7,8-C2B9H8) (3a-3d). The structures of carborane 2d and complexes 3a and 3d were determined by X-ray diffraction. Electrochemistry of the cobalt complexes was studied.
