A Facile and Efficient Deoxygenation of Sulfoxides with Mo(CO)6

The deoxygenation of sulfoxides to sulfides is a valuable transformation in the application of organosulfur compounds in organic synthesis. Accordingly, a good number of methods have been developed for the reduction of sulfoxides to the corresponding sulfides.1 However, they often suffer from serious disadvantages, such as functional group incompati-bility, difficult work-up procedures, harsh reaction condi-tions, or not readily available reagents. Further some of these methods are associated with limitations regarding low yields, prolonged reaction times, and intricate procedures. Therefore, there still exists a search for new improved methods based on easily accessible reagents and operationally simple proce-dures for the reduction of sulfoxides. The use of oxophilic d-block metals have become important in deoxygenation of various types of organic molecules.2 In this regard, the selec
