Crown ethers containing 3,4-thiophenediyl and 3,4-thiophenediylbis(methylene) subunits as a ring constituent were prepared starting from 2,5-bis(ethoxycarbonyl)-3,4-thiophenediol and 2,5-dichloro-3,4-bis(chloromethyl)thiophene, respectively. A Raney nickel desulfurization of the thiophene-containing crown ethers afforded crown ethers having two adjacent side chains, such as a methyl or ethoxycarbonylmethyl
从 2,5-双(乙氧基羰基)-3,4-噻吩二醇和 2,5-二氯-3,4 开始制备含有 3,4-噻吩二基和 3,4-噻吩二基双(亚甲基)亚基作为环成分的冠醚-双(氯甲基)噻吩,分别。含噻吩的冠醚的阮内镍脱硫得到具有两个相邻侧链的冠醚,例如甲基或乙氧基羰基甲基。这些冠醚对碱金属阳离子的萃取能力也通过溶剂萃取法进行了检测。
