Reactions of alkoxymethyl substitutedstyrene derivatives with a stoichiometric and/or catalytic amount of zirconocene-(1-butene) complex (“Cp2Zr“) causes an unexpected zirconocene insertion into benzylic position and/or homolytic coupling reaction of the styrene derivatives.

Benzylzirconocene intermediate, which was readily prepared by the reaction of o-alkoxymethylstyrene with `Cp2Zr' under mild conditions, reacted with allylic halides or phosphates in the presence of catalytic amount of CuCl to give allylated products in good yields.
