Synthesis of [3]Rotaxanes that Utilize the Catalytic Activity of a Macrocyclic Phenanthroline-Cu Complex: Remarkable Effect of the Length of the Axle Precursor
[3]Rotaxanes, which consist of one macrocyclic phenanthroline compound and two axle components, were prepared by the oxidative dimerization of an alkyne compound with bulky tris[4′‐cyclohexyl‐(1,1′‐biphenyl)‐4‐yl]methyl blocking group. The catalyticactivity of a macrocyclicphenanthroline–Cucomplex was utilized to thread the two axle components inside the ring. The alkyne compound with chain of 15

Active metal template Glaser coupling has been used to synthesize a series of rotaxanes consisting of a polyyne, with up to 24 contiguous sp-hybridized carbon atoms, threaded through a variety of macrocycles. Cadiot–Chodkiewicz cross-coupling affords higher yields of rotaxanes than homocoupling. This methodology has been used to prepare [3]rotaxanes with two polyyne chains locked through the same macrocycle
Rotacatenanes were synthesized by the catalytic reaction using a macrocyclic phenanthroline–CuI complex followed by the installation of another ring by the template method. In this approach, the size of the ring component of the rotaxane turns out to be a very important factor for the synthesis of rotacatenanes.

phenanthrolines 3a−e and a tris(biphenyl)methyl derivative 4. [2]Rotaxanes with large ring components (10a,b) were synthesized by the template method, and the stability of the rotaxanes was examined. The study revealed that the tris(biphenyl)methyl group is an effective blockinggroup for the rotaxanes with up to a 33-membered ring. Even a rotaxane with a 37-membered macrocyclic phenanthroline (10b) could

[2]Rotaxanes with large macrocyclic phenanthrolines were prepared by the template method, and the stability of the rotaxanes was examined. Compared to the tris(biphenyl)methyl group, the tris(4-cyclohexylbiphenyl)methyl group was a larger blocking group, and the rate of the dissociation of the components decreased significantly when the thermal stability of a rotaxane with a 41-memebered ring was examined
