STUDIES ON ORGANOLANTHANIDE COMPLEXES. XXIII, REACTION OF ORGANIC HALIDES WITH TRICYCLOPENTADIENYLLANTHANIDES/SODIUM HYDRIDE

Abstract The reductive dehalogenation of aryl and vinyl halides with tricyclopentadienyllanthanide / sodium hydride systems affords, respectively, the corresponding aromatics and alkenes in excellent yields under mild conditions. However, the reaction with alkyl halides generates alkylated products, which yield alkyl cyclopentadienes after hydrolysis. The reaction mechanism has been briefly investigated.
