Synthesis of Novel Dichloroborane Having a Pincer Ligand and its Dehalogenation Reactions

Abstract

To prepare organoboron compounds bearing boron-carbon bonds with unique electronic states, novel dichloroborane having a pincer ligand was synthesized. It was then treated with silver trifluoromethanesulfonate to provide bis(trifluoromethanesulfonyl)borane with considerably covalent boron-oxygen bonds, as evidenced by its X-ray diffraction analysis. The dichloroborane reacted with silver tetrafluoroborate to provide the unexpected borenium ion. Reaction of the dichloroborane with potassium graphite provided an unexpected boron compound.
