Beta-Ketosulfones bearing a phenyl group linked to the carbonyl unit are efficiently desulfonylated using Bu3SnCl/NaBH3CN in tert-butanol at reflux. A 2 equivalent excess of the reducing couple and a catalytic amount of AIBN are required. An ample variety of functionalities remain unaffected under these conditions.

Abstract
Beta-Ketosulfones bearing a phenyl group linked to the carbonyl unit are efficiently desulfonylated using Bu3SnCl/NaBH3CN in tert-butanol at reflux. A 2 equivalent excess of the reducing couple and a catalytic amount of AIBN are required. An ample variety of functionalities remain unaffected under these conditions.File in questo prodotto:
