| Interesting 3-coordinate organoboron compounds can be prepared stoichiometrically or catalytically. For example, those incorporating dimesitylboryl groups [B(mes)2] are usually prepared via reaction of carbon nucleophiles with FB(mes)2 or via alkyne hydroboration using [HB(mes)2]2. Many such products show interesting linear and/or nonlinear optical properties. Alternatively, compounds containing pinacolatoboryl groups [B(pin)] can now be prepared directly by catalytic borylation of C-H bonds in arenes, heteroarenes, and alkenes using appropriate Rh or Ir catalyst precursors. These latter borylated systems can subsequently be used in Suzuki-Miyaura cross-couplings to produce new conjugated organic compounds with interesting optical or biological properties. Aspects of our recent work on the synthesis and properties of such 3-coordinate organoboron compounds will be described. |
