A single-atom iron catalyst was found to exhibit exceptional reactivity in acceptorless dehydrogenative coupling for quinoline synthesis, outperforming known homogeneous and nanocatalyst systems. Detailed characterizations, including aberration-corrected HAADF-STEM, XANES, EXAFS, jointly confirmed the presence of atomically dispersed centers. Various functionalized quinolines were efficiently synthesized from different amino alcohols a range ketones or alcohols. The achieved turnover number (TON) up 10

A facile strategy to increase the chemoselectivity of domino reactions was proposed and successfully applied in α-functionalization ketones. The involved widening activation energy main reaction side through intermolecular interactions, thereby increasing reaction. In reaction, TMSCF3 acted as an excellent reagent which increased nucleophilicity DMF Van der Waals force reduced H2O a hydrogen bond. We found that can difference between using DFT calculations, greatly avoided formation by-products. recycled by rectification, average recovery rate 87.2%. XRD experiments, control experiments were performed support this mechanism. are confident has potential deliver significant practical advancements while simultaneously fostering broader innovation field synthesis.
