Feasible Synthesis of N,O-Bidentate Difluoroboron Chromophores through Direct Functionalization of Quinoxalin-2(1H)-ones with Ketones in One Shot

Organic difluoroboron complexes are a kind of potential platforms for a wide range of applications owing to their excellent photophysical properties. Herein, we have explored a simple and direct synthesis methodology for a library of N,O-bidentate difluoroboron complexes from quinoxalin-2(1H)-ones and ketones in one shot. The photophysical properties of the generated complexes were evaluated and the application potential of these compounds on subcellular imaging was also explored.
