Here we describe a potassium 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, diaryl disulfides and diselenides underwent one-carbon homologation to form dithioacetals and diselenoacetals. Synthesized dithioacetals were transformed into 4-nitrobenzaldehyde and 7-(bis(phenylthio)methyl)-1H-indole.

The electron impact mass spectral studies on some nitrobenzylidene thioacetal derivatives showed two different mechanisms of oxygen transfer from the nitro group to the sulfur containing fragments via intra-and inter-oxygen transfer. The two mechanisms ar

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 e
