一系列雙醯氨為配位基搭配鋅所形成的錯化合物已被合成。之前文獻報導此類形化合物呈現出具有雙核及三核不同的結構。我們試著探討其影響的因素以及其反應機制。
一系列以NNO三牙西苻鹼搭配鋅所形成的錯化合物已被合成。此化合物對乳酸交酯開環聚合反應有極佳的效果。從動力學研究發現，反應數率與乳酸交酯和催化劑皆為一次方的關係。對於外消旋乳酸交酯開環聚合反應的選擇性在二氯甲烷為溶劑，-55度下可高達91%。
以NNO三牙西苻鹼搭配鈣所形成的錯化合物已被合成。此化合物搭配各式各樣的醇類對乳酸交酯開環聚合反應都有極佳的效果。從動力學研究發現，反應數率與乳酸交酯和苯甲醇皆為一次方的關係。

Abstract
Synthesis, characterization and catalytic activities of several b-diketiminato zinc complexes will be presented. Previous reports show that b-diketiminato zinc alkoxides exhibit two different structures, dinuclear or trinuclear. Factors affecting the aggregation of dinuclear and trinuclear zinc complexes and the proposed mechanism on the formation of the structures will also be described.

A series of new dinuclear zinc complexes of the types [LZnEt]2 and [LZn(m-OBn)]2 (where L = NNO-tridentate Schiff base ligand) have been prepared. In addition, the activities of zinc alkoxides, [LZn(m -OBn)]2 toward the ring-opening polymerization of L-lactide have been investigated. Experimental results indicate that the reactivity of [LZn(m -OBn)]2 was dramatically affected by both the electronic and steric effects of the substituents on the Schiff base. The polymerization kinetics using [L2Zn(m -OBn)]2 as an initiator has been studied, and the experimental results reveal that the reaction rate is a first-order, dependent on both [LA] and [[L2Zn(m -OBn)]2]. Furthermore, the heterotactic PLA initiated by [L5Zn(m -OBn)]2 with Pr up to 91% can be achieved in CH2Cl2 at -55 °C.

A novel calcium complex, [(DAIP)2Ca]2 (where DAIP-H = 2-[(2-dimethylamino-ethylimino)methyl]phenol) is prepared in one-pot reaction by the condensation of Ca(OMe)2 with DAIP-H in toluene/THF. In the presence of various alcohols, [(DAIP)2Ca]2 efficiently initiate the ring-opening polymerization of L-lactide in a controlled fashion, yielding functionalized polymers with expectative molecular weight and low polydispersity indexes. In addition, kinetic studies show a first-order dependency on both [LA] and [BnOH]
