In this article we report a non-odorous protocol for the high yield formation of aryl-alkyl sulfides by the reaction of aryl iodides, bromides and boronic acids with elemental sulfur and electron-deficient alkenes, catalyzed by copper ferrite nanoparticles. The catalyst was easily separated using an external magnetic bar and recycled for subsequent runs, its catalytic activity being preserved.

Pummerer rearrangement reactions generate sulfur (II) oxidation state from sulfur (IV) starting materials in the presence of activating reagents. We found unprecedented transformation of vinyl sulfoxide; disulfide formation reactions mediated by atmospheric pressure of carbon dioxide in extended Pummerer rearrangement reactions. Only under CO2 atmosphere, we observed moderate to high yields of disulfide starting from sulfur (IV) starting materials. Investigations on the reaction mechanism revealed that the degradation of the starting materials and the products was significant in the absence of CO2. Further evidence for the suggested reaction mechanism was obtained by a cross-over experiment and a radical trapping reagent.

Antibiotic resistance is a worldwide problem. The synthesis and evaluation of new antimicrobial compounds, without cytotoxicity against human cells, are highly desired. In this paper, the preparation of a class of pyrimidine-derived disulfides is describe
