High Yields

The photocatalytic microchip was demonstrated as an efficient platform of the photocatalytic organic reactions, which features an easy control of the reaction time and light conditions. We demonstrated the photocatalytic decarboxylation and the following adduct reaction inside the microchip and successfully achieved high yields of the products.

Photocatalytic System

A photocatalytic system for the dearomative hydroarylation of benzene derivatives has been developed. Using a combination of an organic photoredox catalyst and an amine reductant, this process operates through a reductive radical-polar crossover mechanism where aryl halide reduction triggers a regioselective cyclization event, giving rise to a range of complex spirocyclic cyclohexadienes. This light-driven protocol functions at room temperature in a green solvent system (aq. MeCN), without the need for precious metal-based catalysts or reagents, or the generation of stoichiometric metal byproducts.
