Article Abstract

We disclose a novel method for the synthesis of fluorescent ,'-chelate organoboron compounds in high efficiency by treatment of aminoquinolates with NaBAr/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 is up to 0.79 in dichloromethane.
