Primary and secondary benzylic carbocations, stabilized by a tricarbonyl-chromium group, gave coupling products with several aromatics or β-dicarbonyl compounds in good yield and this reaction presents a new synthetic method for carbon-carbon bond formation. The chromium complexes of tertiary benzyl alcohols gave dehydrated products without carbon-carbon coupling products under similar conditions.
