Cover Feature: Organo‐Soluble Colloidal MoS₂ Quantum Dots (QDs) as an Efficient Photocatalyst for α‐Amino Phosphonate Synthesis (ChemCatChem 15/2024)

The Cover Feature of this issue highlights the work by Abir Kayal and Mrinmoy De, who describe a method for synthesizing recyclable organo-soluble MoS2 quantum dots (QDs) using a colloidal approach, which exhibits high efficiency as photocatalysts for the synthesis of biologically active α-amino phosphonates. The authors' approach capitalizes on the oxidizing potential of molecular oxygen (O2). Specifically, MoS2 QDs are excited upon absorption of blue light, providing the necessary energy to initiate the formation of reactive iminium ion species from N-phenyl benzylamine, thereby facilitating product formation. Mechanistic analysis has underscored the critical role of MoS2 QDs in generating reactive superoxide radicals from O2 via single electron transfer (SET), highlighting their significance in this process.
