Abstract

The reactivity of thia-crown ethers M1–M3 modified by 2(5H)-furanone fragments relative to nickel(II) and silver(I) ions has been studied. The stability of the complexes was analyzed by spectrophotometry. The thermodynamic parameters of complexation of thia-crown ethers M1–M3 with silver(I) ions in ethanol (95%) and DMSO were determined by isothermal titration calorimetry. The standard enthalpies of formation of the compounds were calculated by the additive group method based on group systematics with Benson-type classification of fragments, including the influence of the nearest-neighbor atoms.

硫冠醚与镍（II）和银(I)离子在乙醇和二甲亚砜中的络合作用

研究了2(5H)-呋喃酮片段修饰的硫冠醚M1-M3与镍（II）和银(I)离子的反应性。用分光光度法分析了配合物的稳定性。采用等温滴定量热法测定了硫冠醚M1-M3与银(I)离子在乙醇（95%）和DMSO中络合的热力学参数。基于基团系统学和片段的benson分类，考虑了最近邻原子的影响，采用加性基团法计算了化合物的标准生成焓。
