(Chemical Equation Presented) A rhodium-catalyzed 1,4-addition of sodium tetraarylborates to β,β-disubstituted α,β-unsaturated ketones is described. Highly efficient asymmetric catalysis has also been achieved by employing a readily available chiral diene

We disclose a novel method for the synthesis of fluorescent N,N'-chelate organoboron compounds in high efficiency by treatment of aminoquinolates with NaBAr4/ R'COOH in the presence of an iodine catalyst. These compounds display high air and thermal stability. A possible catalytic mechanism based on the results of control experiments has been proposed. Fluorescence quantum yield of 3b is up to 0.79 in dichloromethane.

experimental part, p. 1052 - 1063 (2011/04/26)
(Chemical Equation Presented) 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.
