本工作用两种方法合成了高分子配位体,其一为以单体配位体苯乙烯基二苯膦(SDPP)均聚及共聚;其二是从交联聚苯乙烯微球出发的传统方法。将所合成的各种高分子膦配位体与镍的络合物用于催化丁二烯环寡聚反应。结果表明,由单体配位体所得到的高分子配位体在选择性上比均相反应略高,转化率基本相同,但反应速度则低一个数量级,而用传统方法得到的高分子金属络合催化剂,其反应速度比均相反应低两个数量
In this work, polymer ligands were synthesized in two ways, one of which was homopolymerization and copolymerization of styrene-based diphenylphosphine (SDPP) as the monomer ligand and the other was from crosslinked polystyrene microspheres Traditional method The synthesized complexes of various polymeric phosphine ligands with nickel were used to catalyze the butadiene ring oligomerization. The results showed that the polymer ligands obtained from the monomer ligands were slightly more selective and homogeneous than the homogeneous ones, but the reaction rate was an order of magnitude lower. However, with the traditional method, Complex catalyst, the reaction rate lower than the average number of reactions two
