Abstract

N,N,N',N'-tetramethyl-N,N'-bis(sulfo)ethane-1,2-diaminium mesylate ‎‎([TMBSED][Oms]2) is ‎used as a highly efficient and dual-functional catalyst for the one-pot multi-component ‎condensation of 2-naphthol with arylaldehydes and thioacetamide under green, mild (70 °C), ‎and solvent-free conditions. In this reaction, 1-thioamidoalkyl-2-naphthols are produced in ‎high to excellent yields and in relatively short reaction times. In this reaction, products ‎are identified by analysis of its 1H NMR, 13C NMR, and FT-IR data.‎ Moreover, a plausible mechanism based on dual-functionality of the catalyst was proposed.
