Popis: | The synthesis of three boronate esters obtained by reacting 4-fluorophenylboronic ( 1 ), 4-iodophenylboronic ( 2 ) and 3,4-chlorophenylboronic ( 3 ) acids with 2,4,5-trihidroxybenzaldehyde is reported. The structural characterization was determined by spectroscopic and spectrometric techniques. The boron atom was evaluated to acts as Lewis acid center in the reaction with pyridine (Py), triethylamine (TEA) and fluoride anion (F − ). The titration method was followed by UV–Vis and 11 B NMR spectroscopy; results indicate the good interaction with the fluoride ion but poor coordination towards pyridine in solution. |
