摘要

用紫外可见光谱法研究了[Pt(digly)(h2o)] (h2 digly=甘氨酸)与咪唑、吡唑和三唑在25℃水溶液中反应的动力学。在pH=5.05-9.00范围内,I =0.1 mol dm m3下的光谱。揭示了水合配体取代唑基进入的过程。所有产物都通过CHN分析、IR和1h NMR进行了表征。用计算机拟合程序拟合pH变化数据,确定了不同的唑碱对Pt(II)底物的反应性。

Interaction of Some Azole Bases with Platinum(II)-Glycylglycine--Kinetics, Mechanism and Product Characterization
The kinetics of the reaction of [Pt(digly)(H 2 O)] (where H 2 digly=glycylglycine) with imidazole, pyrazole and triazole were studied at 25°C in aqueous medium by UV-Vis. spectroscopy at I =0.1 mol dm m 3 in the range of pH=5.05-9.00. The entry of the azole bases by the substitution of aqua ligand was revealed. All the products have been characterized through CHN analysis, IR and 1 H NMR spectra. The pH variation data were fitted by a computer fit program and the reactivity of the different azole base species towards the Pt(II) substrate ascertained.
