  • Neutral Tricoordinate Organoboron Derivatives Isoelectronic with Amines and Phosphines
    Publication number: 20130190510
    Abstract: Amines and boranes are the archetypical Lewis bases and acids, respectively. The former can readily undergo one-electron oxidation to give radical cations, whereas the latter are easily reduced to afford radical anions. The present invention provides the synthesis of neutral tricoordinate boron derivatives, which act as a Lewis base, and undergoes one-electron oxidation into the corresponding radical cation. The present invention also provides borylene (H—B:) and borinylium (H—B+.) complexes stabilized by two cyclic (alkyl)(amino)carbenes. Ab initio calculations show that the HOMO [Highest Occupied Molecular Orbital] of the borane as well as the SOMO [Singly Occupied Molecular Orbital] of the radical cation are essentially a pair and a single electron in the p(?)-orbital of boron, respectively.
