A heterogeneous catalyst was assembled with ruthenium nanoparticles on carbon nanotubes and used in a mild oxidation method to prepare sulfones from sulfides. The system proved very efficient on the investigated substrates and the products were obtained in high yields.

We report a sequential C-H iodination/organoyl-thiolation of naphthoquinones and their relevant trypanocidal activity. Under a combination of AgSR with a copper source, sulfur-substituted benzenoid quinones were prepared in high yields (generally >90%). This provides an efficient and general method for preparing A-ring modified naphthoquinoidal systems, recognized as a challenge in quinone chemistry.
