Abstract

The adduct of (3-MeC₆H₄)₃B ₃O₃ with an N-heterocyclic carbene (NHC=1,3-diethyl-4,5- dimethylimidazol-2-ylidene) was prepared by reacting 2.5 equiv. of 3-methylphenylboronic acid with 1 equiv. of the NHC. This reaction shows a novel carbene-facilitated condensation of substituted phenylboronic acid monomers. The structure of the compound (3-MeC₆H₄)₃B ₃O₃(NHC) (1) has been characterized by ¹H NMR spectroscopy, elemental analysis, and single-crystal X-ray diffraction studies.
