The activation of a carbon–hydrogen bond in a dimolybdenumcyclononatetraene by oxidation of a metal centre; X-ray crystal structures of [Mo2(µ-C8Me7CH2)(η-C5H5)2][CF3SO3] and [Mo2(µ-C8Me8)(µ-Cl)(η-C5H5)2][SbCl4]·CH2Cl2

Abstract

Protonation of [Mo₂(µ-C₈Me₈)(η-C₅H₅)₂] in CH₂Cl₂ with an excess of CF₃SO₃H or reaction with [Fe(β-C₅H₅)₂][BF₄] leads to the formation of the cation [Mo₂(µ-C₈Me₇CH₂)(η-C₅H₅)₂]⁺, whereas, oxidation with SbCl₆^– affords [Mo₂(µ-C₈Me₈)(η-Cl)(η-C₅H₅)₂][SbCl₄]; both structures are established by X-ray crystallography.
