摘　　要：合成了均相Pd—Mo双核络合物催化剂,由氯甲基化的聚苯乙烯一二乙烯苯树脂可制得2—二苯基膦毗啶—4—次甲基聚苯乙烯树脂,将Pd—Mo双核络合物催化剂同二苯基膦毗啶甲基化聚苯乙烯树脂反应可得固相化催化剂。采用了红外光谱,紫外光谱,核磁共振谱,x—衍射等测定了分子结构,考察了对1,5,9—环十二碳三烯选择加氢催化反应的性能。The synthesis of the homogeneous catalyst of Pd-Mo binuclear complex is reported . Diphenyl phosphine pyrid-ine substituted resin (DPPR) was prepared by reacting o- bromopyridine with chloromethylated styrene divinylben-zene copolymer, and followed by a reaction of the resulted polymer with lithium diphenyl phosphate. The immobilized catalyst was then obtained from a reaction of the homogeneous Pd-Mo binuclear comolex with DPPR. The molecular structure of the catalysts was determined by IR,UV,NMR,and X-ray diffraction analysis. The activity and selectivity of these catalysts were examined in hydrogenation of 1,5,9 - cyclododecatriene.
