摘要: 
以1當量的2,2'-ethylidene-bis(4,6-di-tert-butylphenol)與三烷基鋁(AlR3),在甲苯作溶劑下反應可得到四配位雙體的鋁錯化合物[(EDBP)AlMe]2,再將此鋁錯化合物與2.2當量的醇類(ROH)在甲苯作溶劑下,反應可得到四配位雙體的鋁錯化合物[(EDBP)Al(m-OR)]2,(A:R = Me;B:R = Et;C:R = CH2C6H4-4-OMe),另外以相同之起始物[(EDBP)AlMe]2與2.2當量二苯基甲醇(Benzhydrol)在 四氫口夫喃(Tetrahydrofuran)中反應可得到四配位單體的錯化合物[(EDBP)AlOC(Ph)(THF)](D)。利用A,B,C,D去進行e-caprolactone的開環聚合催化反應,並比較其催化效果。
以N-arylailides與1.2當量的三烷基鋁(AlR3)在正己烷作溶劑下反應可得到四配位雙體的鋁錯化合物[R2Al(m,h2-(4-X-C6H4)NC(Ph)O)]2,(1:R = Me,X = H;2:R = Me,X = OMe;3:R = Me,X = Cl;4:R = Et,X = Cl ;5:R = Me,X = CN);[R2Al(X)(C6H4)NC(Ph)OAlR3],(6:R = Me,X = OMe)。然而以N-arylailides與2.5當量的三烷基鋁(AlR3) 在甲苯作溶劑加熱迴流下,可產生aluminum diketiminates [(h2-Ph-p-X)NC(Ph)C(R')C(Ph)N(Ph-p-X)AlR2],(7:R = Me,R' = H,X = H;8:R = Et,R' = Me,X = H;9:R = Me,R' = H ,X = Cl;10:R = Et,R' = Me,X = Cl)。此反應提供一個迅速且有效的合成aluminum diketiminates 的新方法,其中1,2,3,4,5,6,7,9,10有結構鑑定。Amides的路易士鹼性對配位到鋁上之配位模式影響也將被探討。
