CuOTf-mediated intramolecular diborene hydroarylation

Abstract

Upon complexation to CuOTf, a PMe3-stabilized bis(9-anthryl) diborene slowly undergoes an intramolecular hydroarylation reaction at room temperature. Subsequent triflation of the B–H bond with CuOTf, followed by a PMe3 transfer, finally yields a cyclic sp2–sp3 boryl-substituted boronium triflate salt.
