Titelbild: Droplet‐Based Microfluidics Reveals Insights into Cross‐Coupling Mechanisms over Single‐Atom Heterogeneous Catalysts (Angew. Chem. 20/2024)

Developing improved in-situ characterization tools is crucial for advancing the design of heterogeneous catalysts for organic syntheses. In their Communication (e202401056), Andrew J. deMello, Javier Pérez-Ramírez, Sharon Mitchell and co-workers demonstrate an innovative in-situ X-ray absorption spectroscopy approach using droplet-based microfluidics studying palladium single-atom catalysts in Suzuki-Miyaura coupling. The results showcase the technique′s feasibility and highlight its potential to provide new mechanistic insights.
