将二氮杂１８－冠－６的乙腈溶液分别与２－氯乙基烷基硫醚、２－氯乙基烯丙基硫醚、［２、（２－氯乙基）硫乙基］烷基硫醚在无水碳酸钾存在下反应制得５种新型侧链上含硫原子的双臂套索冠醚和５种新型单臂套索冠醚．它们的收率分别为３７％～７２％和１３％～３７％．此法比其它制备单臂套索冠醚的方法操作简便．
The diazepin 18-crown-6 solution in acetonitrile was mixed with 2-chloroethylalkyl sulfide, 2-chloroethylallyl sulfide, [2, (2-chloroethyl) thioethyl] Sulfides were synthesized in the presence of anhydrous potassium carbonate, and five kinds of novel sulfur-containing arms and five new one-armed lariod crown ethers were prepared. Their yields were 37% -72% and 13% -37%, respectively. This method is more convenient than other methods for preparing one-arm lariding crown ethers.
