概要 Various secondary amine [2]catenanes and [2]rotaxanes were prepd. by borane redn. of the corresponding secondary amide [2]catenanes and [2]rotaxane. Their structures were characterized by NMR, IR, and FAB-MS spectroscopies. The mobility of the components in soln. was examd. by 1H NMR spectroscopy. The substituents on the isophthaloyl units of the catenanes prevented complete circumrotation of the macrocyclic components (half rotation). On the other hand, macrocyclic ring components bearing unsubstituted isophthaloyl units completely circumrotated through the other faster than on the 1H NMR time scale (full rotation). In the case of the secondary amine [2]catenanes, no hydrogen bonding interaction between the secondary amino groups was obsd. A dynamic 1H NMR study showed a highly enhanced mobility of the components of the secondary amine [2]catenanes and [2]rotaxane compared with the corresponding amide compds., even at lower temp.
