Redox-responsive recombination of carbon-carbon bonds on flexible tetrairon cores.
When a brown powder of 2a was dissolved in acetonitrile, 2a was converted to 2b. Equilibrium was reached at a 74:26 molar ratio within 1 week at 303 K. The isomerization proceeds through a cubane-like transition state, in which recombination of a carbon-carbon bond occurs.
