Rotaxane building blocks bearing 3,5‐bis(trifluoromethyl) benzenesulfonate (BTBS) stoppers have been efficiently prepared from a pillar[5]arene derivative, 3,5‐bis(trifluoromethyl) benzenesulfonyl chloride (BTBSCl) and different diols, namely 1,10‐decanediol and 1,12‐dodecanediol. The BTBS moieties of these compounds are good leaving groups and stopper exchange reactions could be achieved by treatment with different nucleophiles thus affording rotaxanes with ester, thioether or ether stoppers.

通过塞子交换策略以多样性为导向制备含[2]轮烷的[5]芳烃

由柱[5]芳烃衍生物、3,5-双(三氟甲基)苯磺酰氯(BTBSCl)和不同的二醇，即1、 10-癸二醇和1,12-十二烷二醇。这些化合物的BTBS部分是良好的离去基团，并且可以通过用不同的亲核试剂处理来实现终止剂交换反应，从而提供具有酯、硫醚或醚终止剂的轮烷。
