Organic difluoroboron complexes is a kind of potential platforms for a wide range of applications owing to their excellent photo-physical properties. Herein, we have explored a simple and direct synthesis methodologies 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 com-plexes were evaluated and the application potential of these compound on subcellular was also explored.

The demand for environmentally-friendly processes in organic synthesis has spurred interest in developing catalyst- and additive-free reactions for the synthesis of valuable organic compounds. Among these, allylic sulfones are a crucial structural motif used in drug development and organic synthesis. Despite several catalytic protocols have been established for the synthesis of allylic sulfones in recent years, the catalyst- and additive-free process has yet to be explored. In this study, we report a highly efficient and green pro-tocol for the synthesis of allylic sulfones from aryl-1, 3-dienes and sulfinic acids. The reaction was conducted under mild conditions using an aerobic atmosphere at room temperature without any catalyst or additive. The procedure demonstrated excellent atom economy, good regio- and chemo-selectivity, simple operation, and scalability. Overall, this method provides a promising strategy for the synthesis of allylic sulfones in a sustainable and cost-effective manner.
