Abstract

A large 40-membered N(4)O(4)S(4) macrocycle (L(2)) was obtained through a 2:2 cyclization of the corresponding dithiol and dichloride as a minor product during the preparation of a 20-membered N(2)O(2)S(2) macrocycle (L(1), 1:1 cyclization product). Each macrocycle was successfully separated from the mixed products and identified. The larger macrocycle L(2) allowed the preparation of its dimercury(II) complex, adopting a one-dimensional (1D) stairway-like polymeric chain linked with the anion. A monomercury(II) complex of the smaller macrocycle L(1) was also prepared. Both complexes and the larger macrocycle L(2) were structurally characterized by the single crystal X-ray analysis.

摘要

一个大环 N(4)O(4)S(4)（L(2)）由相应的二硫醇和二氯化物通过 2:2 环化反应形成，是在制备 20 元大环 N(2)O(2)S(2)（L(1)）的过程中作为副产物得到的（1:1 环化产物）。每个大环都成功地从混合产物中分离出来并进行了鉴定。大环 L(2)可以制备其二汞(II)配合物，采用一维（1D）阶梯状聚合物链与阴离子相连。较小大环 L(1)的单汞(II)配合物也被制备出来。通过单晶 X 射线分析对配合物和较大大环 L(2)进行了结构表征。
