Selective aerobic oxidation of sulfides to sulfoxides catalyzed by coenzyme NAD+ models

Coenzyme NAD(+) models can be applied in the photooxygenation of sulfides to sulfoxides as organocatalysts at room temperature. A series of sulfoxides are synthesized easily with this protocol and the possible mechanism is discussed. This procedure provides a reliable approach to the clean production of useful sulfoxides in synthetic chemistry. (C) 2010 Elsevier Ltd. All rights reserved.
