Iron (II)-and Manganese(I)-Carborane Complexes Formed Through Metal-Carbon sigma-Bonds

摘要

Reaction of 1-lithiocarboranes with manganese pentacarbonyl bromide and cyclopentadienyl iron dicarbonyl iodide gives rise to a series of stable neutral derivatives containing a metal-carbon sigma-bond. Reaction of 1,10-dilithio-1,10-dicarba-closo-decaborane(10), formed from 1,10-dicarba-closo-decaborane(10) and two mole equivalents of n-butyllithium in ethereal solvents, with 2 mole equivalents of cyclopentadienyl iron dicarbonyl iodide, gives rise to an analogous derivative containing two non-chelating metal-carbon sigma bonds. The preparation, characterization, reactions, and proposed structures of these complexes are discussed. (Author)
