Aryl 2- pyridyl sulfoxides, reactions with

Reactions of organomagnesium compounds with sulfoxides often result in ligand exchange [31], and may be complicated by a- or ortho metallation. However, in some cases, notably with 2-pyridyl aryl sulfoxides, reactions with arylmagnesium halides give useful yields of products from displacement of the aryl sulfoxido group [32, 33], e.g. [32]... 

Diaryl Sulfoxides. Optically active diaryl sulfoxides are prepared by reaction of an aryl Grignard with (—)-menthyl (S)-p-toluenesulfinate 2,5-dimethoxyphenyl p-toly 1 sulfoxide (4), a precursor of sulfinyl quinones, and 3-pyridyl p-tolyl sulfoxide (5),...
