Outline of Final Research Achievements

This proposal was conceived form the recent discovery that a certain boron compounds underwent the reversible B-B bond formation upon reduction and reoxidation. On the basis of this finding, it is expected that the electrons, when introduced into the array of the vacant 2p orbitals of boron, can migrate with a very small activation energy in the array. In order to verify this assumption, a novel benzene derivative, which is substituted by six boron substituents, were designed. In the course of the synthetic study of this hexaborylbenzene compound, we happened to discover novel reaction that allowed a facile construction of boron-containing pi-conjugated framework and succeeded in the synthesis of a variety of extended π-conjugated molecules.
