Silica-PSCl3: A mild and efficient reagent for deoxygenation of sulfoxides

A new solid supported reagent, silica-PSCl3, has been developed for deoxygenation of sulfoxides. With this reagent, conversion of sulfoxides to sulfides occurred cleanly and efficiently at room temperature. Facile isolation of the product was achieved by simple filtration of the by-products without any extensive workup.
