Halonium and Chalconium Salt-Catalyzed Schiff Condensation: Kinetics and DFT Insights into Organocatalyst Activity Parameters

Schiff condensation between 4-methylbenzaldehyde and 2-aminopyridine, catalyzed by chloronium, bromonium, iodonium triflates, as well as sulfonium, selenonium, and telluronium triflates, was investigated. ¹H NMR monitoring revealed that the catalytic activity...
