The synergistic effect of a novel photocatalyst based on triazine with 2-aminoanthraquinone for the Beckmann rearrangement in batch and a simple hand-made continuous flow photocatalytic reactor†

The Beckmann rearrangement is a fundamental organic transformation that plays an indispensable role in the synthesis of various functionalized compounds. In recent years, the development of efficient and selective catalysts for this reaction has garnered significant attention. In this study, we investigate the synergetic effect of a novel triazine-based photocatalyst in combination with 2-aminoanthraquinone in the Beckmann rearrangement under visible light irradiation. The triazine-based photocatalyst by incorporating 2-aminoanthraquinone, with its unique structural properties and high photocatalytic activity, offers promising potential for enhancing the efficiency and selectivity of the Beckmann rearrangement. Furthermore, we provide insights into a simple, handmade, continuous-flow photocatalytic reactor system that allows us to perform large-scale Beckmann rearrangement in a shorter time with reasonable efficiency. Overall, this study highlights the synergetic effect of a novel triazine-based photocatalyst with 2-aminoanthraquinone in the Beckmann rearrangement, offering new avenues for synthesizing functionalized compounds with improved efficiency and selectivity.
