Palladium-catalyzed decarboxylative ortho-arylation of 2-pyridyl sulfoxides with benzoyl peroxides

A palladium catalyzed efficient strategy for regio-selective ortho-arylation of sulfoxides with benzoyl peroxides via decarboxylation has been developed. This reaction proceeds smoothly, tolerates a variety of functional groups, and provides easy access to the synthesis of different biaryl compounds.
