tert-butoxide-mediated regioselective direct C–S bond formation at the C(sp3)–H position of nitrotoluenes with disulfides in DMSO at room temperature. The developed reaction generated, in good yields, various dithioacetals having OMe, halogen, and NH2 functionalities at various positions of the arene rings of the disulfides. Interestingly, in the absence of nitrotoluene, diaryldisulfides and diselenides underwent one-carbon

Sulfated zirconia effectively catalyzes the reaction of carbonyl compounds with 1,2-ethanedithiol or thiophenol to afford the corresponding dithioacetals as useful organosulfur synthons. Isolation of pure products in high yields by simple filtration and evaporation is an important feature of this method.
