【摘要】 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．更多还原

【Abstract】 Five new bibracchial lariat Ethers(double armed diaza crown ethers)containing sulfur donor atoms in the side arms were synthesized in 37%─72%yield by treating the acetonitrile solution of diaza-18-crown-6 with 2-chloroethyl alkyl sulfide,2-chloro allyl sulfide,[2-(2-chloroethyl)thioethyl]alkyl sulfide in the presence of anhydrous sodium carbonate.The corresponding lariat ethers(single armed diaza crown ethers) were obtained simutaneously in 13%─37%yield. Therefore this is a facile method for the synthesis of single armed diaza crown ethers.更多还原
