Abstract

Abstract The crystalline water-soluble, σ-bonded dichlorotris(pyridine)benzylchromium(III), dichlorotris(pyridine)( o-chlorobenzyl)chromium(III) and dichlorotris(pyridine)( p-chlorobenzyl)chromium(III) complexes have been isolated from the reaction of dichlorobis(pyridine)chromium(II) and the appropriate benzyl halides in pyridine solution. Solvated monobenzylchromium dichloride, prepared by the Grignard route, is converted with water to the penta-aquobenzylchromium(III) cation and with pyridine to the crystalline dichlorotris(pyridine)benzylchromium(II). The crystalline monobenzylchromium compound acts both as a source of benzyl anions and as a source of benzyI radicals.
