  reaction of cis-Re(CO)4(PR3)Me (R=Ph, Cy) with the Lewis acid B(C6F5)3 was studied by NMR spectroscopy, and was found to provide an equilibrium mixture of the solvent-coordinated complex [cis-Re(CO)4(PR3)(ClCH2Cl)][MeB(C6F5)3] and the reactants. Reaction of cis-Re(CO)4(PR3)Me with HX (X=H, SiEt3) in the presence of B(C6F5)3 at low temperature yielded the σ-bonded complexes [cis-Re(CO)4(PR3)(η2-HX)][MeB(C6F5)3]

  The solvent-coordinated complexes [cis-Re(CO)(4)(PR3)(S)][BArF] (R = Ph, Pr-i, Cy BArF = [B(3,5-(CF3)(2)C6H3)(4)](-)) for S = Et2O. CH(2)Chl(2) and NC5F5 have been prepared from reaction of the neutral methyl precursors, cis-Re-(CO)(4)(PR3)(Me), with either [H(OEt2)(2)][BArF] or [Ph3C][BArF] in the appropriate solvent. A crystal structure of the complex [cis-Re(CO)(4)((PPr3)-Pr-i)(ClCH2Cl)][BArF] shows that the dichloromethane ligand is coordinated through one chlorine, with an Re-Cl distance of 2.554(2) Angstrom. The first example of a structurally characterized pentafluoropyridine complex of rhenium was also determined, [cis-Re(CO)(4)((PPr3)-Pr-i)(NC5F5)][BArF], with an Re-N distance of 2.319(5) Angstrom. Activation of C-CI bonds in the dichloromethane complexes result in the formation of the chloride-bridged dimers, [Cis-Re(CO)(4)(PR3)](2)(mu-Cl)}BArF}, and the X-ray structures of the Ph and Cy derivatives were determined.
• B–C activation in highly alkylated carborane monoanions partnered with cationic transition metal fragments: observations and comments

  Cage decomposition products of the highly methylated, weakly coordinating, carborane anion [1-H-closo-CB11Me11](-) are described. These arise both from well-defined metal complexes of [1-H-closo-CB11Me11](-) that already have BCH3 (...) [M] interactions and from attempts to partner this anion with other metal centres. In all cases the decomposition results in B-CH3 bond cleavage and solvent activation to form products with B-aryl or B-Cl vertices. (c) 2004 Published by Elsevier B.V.
