Abstract

A novel [2]catenane consisted of two cyclic tetramine units (6) was prepared and characterized in terms of mobility of the units. The preparation of 6 was performed by reduction of the corresponding cyclic octamide-type [2]catenane (3) with borane. Varying temperature NMR study indicated that the units of 6 actually move or rotate quite freely unlike those of 3, evidently suggesting a noncovalently bonded molecule without attractive interaction1 between the two units.
