Abstract
Chelate exo-nido-ruthenacarboranes exo-5,6,10-[RuCl(Ph2P(CH2)4PPh2)]-5,6,10-(μ-H)3-10-H-7,8-R,R′-nido-7,8-C2B9H6 (R, R′ = H, PhCH2) were synthesized by the direct method using the reaction of Cl2Ru(PPh3)(Ph2P(CH2)4PPh2) with [7,8-R,R′-nido-7,8-C2B9H10][K] in benzene. Unsubstituted exo-nido-ruthenacarborane (R, R′ = H) was used in situ for the synthesis of the dinuclear Ru-Cu exo-closo cluster of the formula exo-closo-(Ph3P)Cu(μ-H)Ru(Ph2P(CH2)4PPh2)(η5-C2B9H11). The isomerism of the complex and the crystal structure were studied by NMR spectroscopy and X-ray diffraction. The catalytic activity of the cluster in the atom transfer radical polymerization of methyl methacrylate was investigated.
