摘要
本文应用1HNMR对Gr（Ⅱ）-Gly-H2O系统中配体的交换反应进行动力学研究.通过变化系统的pH值.Gly的浓度及温度,证明了常温下Gly配体的交换极慢,且与Gly浓度为二级交换过程.由于Gly进入配位,使配体水的质子活动性减小.
The present paper carried out the study using, 'HNMR on the exchange kinetics of system in Cr( I )-Gly -H2O. In this System, ligand exchange reaction is extremely slow varying with the PH、Gly concentration and temperature,then a second-order process to Gly exchange has been cofirmed. When there exists Gly,the lability of protons of ligand water is weaken.
