Hydrogenation of sulfoxides to sulfides under mild conditions using ruthenium nanoparticle catalysts

The first demonstration of the hydrogenation of sulfoxides under atmospheric H2 pressure is reported. The highly efficient reaction is facilitated by a heterogeneous Ru nanoparticle catalyst. The mild reaction conditions enable the selective hydrogenation of a wide range of functionalized sulfoxides to the corresponding sulfides. The high redox ability of RuO x nanoparticles plays a key role in the hydrogenation.

Anchimeric assistance of the sulfinyl group in the hydrolysis of cyano groups: A new mild method for the reduction of sulfoxides

Conditions to achieve reductive hydrolysis of β-cyanosulfoxides into their corresponding β-sulfenylamides are reported. The anchimeric assistance of the sulfinyl oxygen in the hydrolysis of the cyano group is proposed to explain the mild condition required to achieve it and several proofs supporting this assumption are indicated. From these results a new mild method to transform sulfoxides into sulfides has been developed.
