One-electron oxidation of 2,2-dimethyl-2-silaindane by potassium 12-tungstocobaltate(III). Lack of evidence for stereoelectronic effects on the cleavage of a β-carbon–silicon bond in an aromatic cation radical

Abstract

The one-electron transfer oxidation of 2,2-dimethyl-2-silaindane by K5CoIIIW12O40 leads, in a slow step, to a radical cation which then undergoes fast C–Si bond cleavage, thus indicating that the rate of this cleavage is not significantly affected by the orientation of the C–Si bond with respect to the aromatic system.
