Box 19395‐3697 Tehran, Iran Journal Article 2019 01 09 Nano-silica-bonded 3-<em>n</em>-propyl-1-sulfonic acid imidazolium chloride (nano-SB-[PSIM]Cl) was applied as a highly efficient, general and heterogeneous catalyst for one pot multi-component reaction of 2-naphthol, arylaldehydes, and thioacetamide leading to 1-thioamidolakyl-2-naphthols. All reactions proceeded with excellent yields in short times under solvent-free conditions. Our protocol was superior than most of the reported methods for the preparation of 1-thioamidolakyl-2-naphthols in terms of some factors included relatively short reaction times, moderate to high yields, and absence of organic solvents.     https://icc.journals.pnu.ac.ir/article_6283_d95b953daf670bb248057890c0207fc5.pdf
