ABSTRACT:
There is disclosed a process for preparing sulfonyl acids from mercaptans in a single reactor. The mercaptan is converted to a mercaptide and reacted with an acrylic acid or salt thereof in a basic reaction medium. After formation of the thioether, the reaction medium is treated with chlorine gas to oxidize the thioether to the sulfone. Mild conditions and readily available starting materials render the method capable of preparing such acids efficiently in large scale amounts.
