Abstract

<UFIGR ID="ol0484557n00001">The mild and efficient reaction between triethyl phosphite and benzylic azides allows us not only to construct rotaxanes in high yield from dibenzo[24]crown-8 (DB24C8) and dibenzylammonium (DBA<SUP>+</SUP>)-derived threads but also to incorporate di(p-toluidine)[24]crown-8, which binds DBA<SUP>+</SUP> ions much more weakly than does DB24C8, into a corresponding [2]rotaxane.
