Abstract:
A reproducible metallocyclic motif containing amino-acid functionalised aromatic diimides has been employed to demonstrate remarkable control over entanglement topologies. [2]-Catenane and pseudo-rotaxane units give rise to 1D → 2D polycatenation, the formation of which can be sterically prevented, and a unique 1D → 3D polyrotaxane.

Selection Rules: Thermal Activation
Conjugated systems containing an even number of π-electron pairs undergo a conrotatory ring closure. For example, thermal electrocyclization of (2E,4E)-2,4-hexadiene, a conjugated diene containing two π-electron pairs, gives trans-3,4-dimethylcyclobutene.

Conformations of Cyclohexane
The chair form is the most stable and derives its name from its resemblance to the “easy chair.” In the chair conformation, two carbon atoms are arranged out-of-plane — one above and one below, minimizing the torsional strain. In the chair form, the bond angle is very close to the ideal...
