4-叔丁基苯硫酚在自由基条件下与具有末端α,β-不饱和酯基的假轮烷进行共轭加成,得到相应的芳基硫醚封端的轮烷,而4-叔丁基苯亚磺酸钠在酸性条件下进行共轭加成,也得到芳基砜封端的轮烷。
Conjugate addition of 4-tert-butylbenzenethiol to pseudorotaxane having terminal α,β-unsaturated ester group under radical condition afforded the corresponding aryl sulfide-capped rotaxane, while conjugate addition of sodium 4-tert-butylbenzenesulfinate under acidic condition also yielded aryl sulfone-capped rotaxane.
