An efficient and facile copper(II) acetylacetonate catalyzed synthesis of functionalized bis(arylmethyl)zinc reagents from arylmethyl halides followed by olefination with aromatic aldehydes gives (E)-stilbenes in good yields. Aluminum trichloride was found to be the key ingredient in these reactions.
