Sulfur ylides are well-known to undergo sigmatropic rearrangement reaction. Herein, we describe a novel reactivity of sulfur ylides, which provides access to the product of a formal functional group metathesis upon dealkylative interception of the rearrangement process. Using a simple iron catalyst and in situ generated diazoalkanes this method provides access to α-mercaptoacetonitrile derivatives.

Reaction between benzaldehyde and methyl α-benzylsulfonylacetate furnishes methyl (E)-α-benzylsulfonyl-β-phenylacrylate as the exclusive Knoevenagel adduct. The related condensations between α-benzylsulfonylacetonitrile and paraformaldehyde furnish trans-1-benzylsulfonyl-2-phenylcyclopropane-1-carbonitrile in modest yields. These product structures are established by X-ray crystallographic analysis. Phenylsulfene is ruled out as an intermediate in the formation of the cyclopropane.
Palladium-Catalyzed Synthesis of Allylic and Benzylic Sulifides from the Corresponding Dithiocarbonates

Allylic and benzylic sulfides are prepared from O-(2-alkenyl) or S-(2-alkenyl) S-alkyl and O-benzyl S-alkyl dithiocarbonates in the presence of palladium(0)-phosphine complex as a catalyst.
