Highly efficient synthesis of [3]- and [5]-rotaxanes consisting of crown ether and a sec-ammonium salt

[3]- and [5]-rotaxanes consisting of crown ether and ammonium salts were synthesized in high yields by a tributylphosphine-catalyzed end-capping method which provides a simple and practical means of obtaining higher-order rotaxanes.
