Alkyl-15-crown-5 and alkyl-12-crown-4 were prepared via polyethylene glycol β-haloalkyl ethers in two steps from terminal olefins, and their complexing ability with cations of alkali and alkaline earth metals was measured by using 1H NMR; it was found to be almost identified with that of the corresponding unsubstituted crown ether. A new type of alkyl crown ether with a chloro substituent could also be synthesized
以聚乙二醇β-卤代烷基醚为原料,以末端烯烃为原料,通过两步法制备了烷基15-冠5和烷基12-冠4,并用1H NMR测定了它们与碱金属和碱土金属阳离子的络合能力;发现它几乎与相应的未取代冠醚相同。用该方法还可以合成一种新型的带有氯取代基的烷基冠醚。
