Copper(I)-catalyzed or mediated reactions of five-membered zirconacycles with propargyl or allyl halides afforded a variety of useful vinylated cyclic compounds, including highly substituted styrenes, vinylcyclohexadienes and methylenecycloheptadienes, via tandem inter–intramolecular allylation reactions.
五元氧化锆环与炔丙基或烯丙基卤的铜(I)催化或介导反应可通过串联的分子间烯丙基化反应提供各种有用的乙烯基化的环状化合物,包括高度取代的苯乙烯,乙烯基环己二烯和亚甲基环庚二烯。
