Abstract:
A [2]rotaxane undergoes switching of its bis-p-xylyl-[26]crown-6 (BPX26C6) component away from its guanidinium station toward its 2,2'-bipyridyl and carbamate stations upon the addition and removal of Zn(2+) and PO(4)(3-) ions, respectively.

Thermal Electrocyclic Reactions: Stereochemistry
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.
