Abstract
Visible light-mediated Cross-Dehydrogenative Coupling of Xanthene with β-keto moieties has been developed using MoS2 Quantum Dot (QD) as a photoredox catalyst. Interesting features of this strategy includes circumventing the requisite of pre-functionalized starting material, broad substrate scope, mild reaction condition, water as a solvent system, and recyclability of catalyst up to six cycles without loss of yield and selectivity. We have also enlightened the Kinetic Solvent Isotope Effect (KSIE) by scrutinizing the aspect of triplet-to-triplet photo energy transfer. The reductive quenching mechanism of QD photocatalyst has been endorsed by cyclic voltametric study.
