S,S-螯合配位的Pd(Ⅱ)配合物的合成及其对二肽水解促进作用的研究

THE SYNTHESIS ON NEW S,SCHELATED Pd() COMPLEXES AND\= THEIR PROMOTER ACTION ON THE HYDROLYTIC\= CLEAVAGE OF DIPEPITIDE

本文报道合成了一系列Ｓ，Ｓ－型螯合配体—１，２－二苯硫基乙烷及其衍生物。制备了它们与Ｐｄ（Ⅱ）形成的配合物，并研究了这些配合物促进下的二肽水解反应动力学。结果发现这些配合物对二肽的水解反应有促进作用，该水解反应是通过配位水的进攻机理进行的。

; We have successfully prepared 1,2dibenzenesulfenyl ethane and a series of its derivatives, and the corresponding chelates of them with Pd() were also prepared. The influence of these complexes on the hydrolysis of dipeptide was investigated using \+1H NMR techniques. It was found that the hydrolysis rate was accelerated by these complexes, and the rate increased with the increasing number of aqueous ligands.\=\;
