Synthesis of Sulfoxide Derivatives
Deprotonation of the weakly acidic α-protons of sulfoxides with LiOtBu and the use of a palladium phosphine complex as catalyst facilitates an α-arylation of various aryl methyl sulfoxides with aryl bromides. More challenging coupling partners, such as alkyl methyl sulfoxides (including dimethyl sulfoxide) and aryl chlorides proved to be suitable under optimized conditions.
