    • Although the calculated average yield for each of the nine reactions performed is 91, based on the isolated yield of 44% for the final [4]rotaxane, the effective average yield per step is most likely even higher than this calculated value as a result of the unavoidable attrition that takes place during the isolation of products which are amphiphilic salts. These kinds of compounds are notoriously difficult to obtain pure without loss of some pure compound on the stationary phase SiO2
