摘要

Summary: Dialkyl or alkyl aryl thioethers, including nucleoside thioethers, undergo virtually quantitative conversion to a-fluoro thioethers with (diethy1amino) sulfur trifluoride (DAST) in dichloromethane at ambient temperature. Antimony (II1) chloride catalyzes the process. a- Fluoro thioethers have recently been employed in syntheses of novel biologically active compoundsM and in preparations of a-fluoro sulfoxidesPp6 sulfones,'and sulfoximinese ...
