[摘要]：A new, mild, one-pot method for the synthesis of cyclobutabenzenes, e.g., I, by the zirconium-promoted cross-coupling reaction of aryllithium compds. and alkenyl bromides is reported. Formation of an arynezirconocene complex and its regioselective coupling with an alkenyl bromide are the key steps of the process. This method allows the regio- and diastereoselective synthesis of functionalized cyclobutabenzene derivs. from simple and easily available starting materials.
