, p. 911 - 916 (2010)
Reactions of O-mesitylenesulfonylhydroxylamine with 2-(methylsulfanyl) pyrazine, 2-(methylsulfanyl) pyrimidine, and 3,5-dimethyl-2-(methylsulfanyl) pyrimidines involve both sulfur and nitrogen atoms. The amination products at the sulfur atom prevail in th

A reaction of SH-containing heterocycles with dimethyl carbonate (DMC) in the presence of K2CO3 and tetrabutylammonium bromide (Bu4NBr) gave heteroaryl methyl thioethers in 44-93% yields. The reaction was carried out under mild conditions. This method provided a useful synthetic method for preparation of various heteroaryl methyl thioethers without the use of toxic methylic halides or dimethyl sulfate.
An easy and fast ultrasonic selective S-alkylation of hetaryl thiols at room temperature

experimental part, p. 783 - 788 (2011/10/09)
A series of 2-alkylthio derivatives of hetaryl thiols were synthesized by selective S-alkylation with alkyl halides (bromides and iodides) with ultrasonic irradiation at room temperature. The reaction was found to be generally applicable to hetaryl thiol derivatives with different substituents in the aromatic nucleus and various alkyl halides. The reaction gives high to excellent yields of products with high purity.
