Preparation of Triethylammonium Tetra-Arylborates (TEATABs): Coupling Partners for the Suzuki Reaction

Abstract

Abstract Six triethylammonium tetra-arylborates (TEATABs) were synthesized via a convenient reproducible procedure and characterized by spectroscopic methods (1H, 13C, 11B NMR and electrospray ionization–high-resolution mass spectrometry). The compounds could be stored at ambient temperature and were useful as reactants in the Suzuki reaction in aqueous conditions when using commercially available catalysts.
