Four kinds of novel lanthanocene complexes were synthesized in reasonable yield by the reaction of equimolar quantity of sodium salt of tridentate Schiff base [N-(2-methoxyphenyl)salicylideneimine] with indenyl lanthanoid dichloride tetrahydrofuranate in tetrahydrofuran. All the complexes after purification were characterized by MS and EA, respectively. These complexes isomerized successfully the 1,5-hexadiene into a mixture of products such as 1,4-hexadiene, 2,4-hexadiene,1,3-hexadiene, methylenecyclopentane and methylcyclopentene. Similarly they also proved effective for the polymerization of methylmethacrylate (MMA), 56.45 % yield and high molecular weight (355 × 103).
通过等摩尔量的三叉席夫碱[N-(2-甲氧基苯基)水杨亚胺]钠盐与茚基二氯化镧四氢呋喃酸盐在四氢呋喃中的反应,合成了四种新型二氯化镧配合物。纯化后的所有络合物都分别通过 MS 和 EA 进行了表征。这些复合物成功地将 1,5-hexadiene 异构化为 1,4-hexadiene 、2,4-hexadiene、1,3-hexadiene、methylenecyclopentane 和 methylcyclopentene 等混合物。同样,它们也被证明对甲基丙烯酸甲酯(MMA)的聚合有效,产率为 56.45%,分子量高(355 × 103)。
