摘　　要：以交联聚苯乙烯为载体,制得含磷配体的固载零价镍催化剂。用该催化剂催化丁二烯环三聚反应得到了1,5,9-全反式环十二三烯。文章论述了催化剂结构对丁二烯环三聚反应活性及选择性的影响。The cyclotrimerization of 1,2-butadiene with the crosslinked polystyrene-supported Nick- el(0)was studied in this paper.The cyclotrimer of 1,3-butadiene,t,t,t-1,5,9 cyclododecatriene was prepared using catalysts ■-CH_2-P(Ph)_2-Ni(0) and ■-P(n-Bu)_2-Ni(0).The effects of phos- phine ligand and the structure of catalysts on the selectivity and reactivity of the cyclotrimerization were discussed.
