One-electron oxidation is generally expected to weaken a bond in a molecule or, on rare occasions, break it. Removing one electron from a small propellane cage has now been shown to break three lateral bonds, opening it up into an acyclic cation after a cascade of rearrangements, initiated by vibronic coupling.
Nature reduces dinitrogen under mild conditions using nitrogenases, the most active of which contains molybdenum and iron. The only abiological dinitrogen reduction catalyst that avoids the harsh conditions of the Haber–Bosch process contains just molybdenum.
Advances in transduction of electrochemical activity through surface plasmon resonance afford new opportunities for spatially and temporally resolved studies of interfaces.
