A novel ammonium iodide-induced sulfenylation of 4-hydroxycoumarins or 4-hydroxyquinolinones by using an aryl- or alkylsulfonyl chloride as the sulfur source gave a wide range of 3-sulfanyl-4-hydroxycoumarins or 3-sulfanyl-4-hydroxyquinolinones, respectiv

An efficient approach for the direct sulfanylation of 4-hydroxyquinolinones and 4-hydroxypyridones with aryl thiols in the presence of CuI/DMSO has been developed. The substrate scope is broad, allowing facile synthesis of a range of structurally diverse 3-sulfanyl-4-hydroxyquinolinones and 3-sulfanyl-4-hydroxypyridones in good efficiency.
Sulfenylation of heterocyclic 1,3-dicarbonyl systems: 4-Hydroxy-2-pyrones, 6-hydroxy-4-pyrimidones, 4-hydroxy-2-pyridones, 4-hydroxy-6-pyridazinones, and 5-hydroxy-3-pyrazolones

Anions of enolized heteroaromatic 1,3-dicarbonyl systems, such as the title compounds 1, 9, 14, and 19, react in dimethylformamide in the presence of potassium carbonate with diaryl disulfides 2 to yield arylsulfenyl derivatives (3, 10, 15, 20). The arylt
