In situ switching of the associated anions of a rotaxane catalyst between Cl and TFPB exposes its dialkylammonium and imidazolium stations, respectively, thereby selectively catalyzing the reactions of a mixture of trans-cinnamaldehyde and an aliphatic thiol to yield the Michael adduct and the thioacetal product, respectively.
轮烷催化剂相关阴离子在 Cl 和 TFPB 之间的原位切换，分别暴露了其二烷基铵和咪唑鎓位点，从而分别选择性催化反式肉桂醛与脂肪族硫醇混合物的反应，生成迈克尔加成物和硫代缩醛产物。
