发明名称 Process for preparating sulfonyl acids.
摘要 <p>There is disclosed a process for preparing sulfonyl acids from mercaptans in a single reactor. The mercaptan is converted to mercaptide and reacted with a lactone or lactam in an organic solvent which is removed after formation of a thioether containing acid. Water is provided as a solvent for the oxidation of the thioether to the sulfone. Mild conditions and readily available starting materials render the method capable of preparing such acids in large scale amounts.</p>
