Several iiew diaryl sulfides and the corresponding sulfones were prepared for study iii one extensive program in this Laboratory. Preparation of the sulfides was somewhat different from published procedures. However, conversioii of these sulfides to their sulfones was accomplished by the standard hydrogen peroxide oxidatioii. Metal thiopheiiolates have often hcen employed to displace the halogen in aryl halides forming diaryl sulfides. Aromatic ...
