An odd molecule with an unpaired electron: Reduction of a cationic borane bearing an α-methylium center leads to the formation of a neutral radical, which has been studied by X-ray analysis and EPR spectroscopy. The computed spin density (see picture, right) of this radical shows substantial localization of the unpaired electron in a polarized BC π-bonding orbital, a conclusion corroborated by an unusually short BC bond.
