Bimolecular hydrogen transfer in phenalene by a stepwise ene-like reaction mechanism.
For the hydrogen transfer of phenalene, a bimolecular ene-like mechanism is proposed, which is preferable over the hypothesized unimolecular rearrangement in the literature. Unique SOMO-SOMO pi-bonding of phenalenyl reduces the barriers of pericyclic reactions significantly. Pi-bonding between radicals is being recognized as a novel type of bonding interaction. This paper adds to the use of this interaction by pointing out its effect on reaction barriers.
