A facile approach for thioetherification of 4-hydroxycoumarins with arylsulfonyl hydrazides promoted by tetrabutylammonium iodide in the presence of hydrochloric acid was developed generating a series of 3-arylthio-4-hydroxycoumarins in 65%~94% yields. Broad scope and easy availability of substrates, simple operation and high yields of products are the advantages of this method.
Key words: arylsulfonyl hydrazide, 4-hydroxycoumarin, thioetherification, tetrabutylammonium iodide
