Abstract
Conjugate addition of 4-tert-butylbenzenethiol to pseudorotaxane having ter minal alpha, beta-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 ar yl sulfone-capped rotaxane.
