Abstract 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...

Description
Summary:Abstract 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.
