Catalytic Thia‐Sommelet—Hauser Rearrangement: Application to the Synthesis of Oxindoles.

A series of 3-arylthio-1,3-disubstituted-oxindoles were prepared in good yields by the reaction of α-diazocarbonyl compounds and sulfenamides. The reaction involves a Rh-catalyzed thia-Sommelet-Hauser-type rearrangement.
