In this paper, a one-step copper-catalyzed procedure for oxidative coupling of active methylene compounds including cyclic β-diketones, cyclic β-ketoesters and 5-pyrazolone with benzenethiols is described. Benzenethiols are in situ generated in the reaction mixture from aryl halides and thiourea as sulfur transfer reagent. α-Thioaryl compounds are obtained in excellent yields and in short reaction time via the process which is free from the foul smell of thiols.
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
