Abstract:
A C-C bond migration event during the cycloisomerization of 1,6-enynes is described. Two different catalytic systems, iridium- or platinum-based, are able to induce this process. Alkyl migrations of larger rings and acyclic groups indicate that the reaction is not fully driven by the release of ring strain.

Stability of Substituted Cyclohexanes
The two chair conformations of cyclohexanes undergo rapid interconversion at room temperature. Both forms have identical energies and stabilities, each comprising equal amounts of the equilibrium mixture. Replacing a hydrogen atom with a functional group makes the two conformations energetically non-equivalent.
For example, in...

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.
