Synthesis of Highly Functionalizable Symmetrically and Unsymmetrically Substituted Triarylboranes from BenchâStable Boron Precursors
A novel and convenient methodology for the one-pot synthesis of sterically congested triarylboranes by using bench-stable aryltrifluoroborates as the boron source is reported. This procedure gives systematic access to symmetrically and unsymmetrically substituted triarylboranes of the types BArArâ and BArAr'Arââ, respectively. Three unsymmetrically substituted triarylboranes as well as their iridium-catalyzed CâH borylation products are reported. These borylated triarylboranes contain one to three positions that can subsequently be orthogonally functionalized in follow-up reactions, such as Suzuki-Miyaura cross-couplings or Sonogashira couplings
