Palladium-catalyzed benzylic direct arylation of benzyl sulfones with aryl halides
An effective palladium catalyst system for the direct arylation of benzyl sulfones with aryl halides has been developed. The catalytic reaction provides a facile route to diarylmethyl sulfones. The products can be transformed further via desulfonylative functionalization mediated by aluminum compounds.

A useful Pd-catalyzed Negishi coupling approach to benzylic sulfonamide derivatives
(Chemical Equation Presented) A mild catalytic system to access diversely functionalized benzylic sulfonamides has been developed. Palladium-catalyzed α-arylation by Negishi cross-coupling of sulfonamide-stabilized anions and a wide range of aryl iodides, bromides, and triflates constitutes a practical strategy for the synthesis of various benzylic sulfonamides.

Palladium-catalysed arylation of sulfonamide stabilised enolates
α-Arylation of methanesulfonamides using palladium catalysis is described. For example, treatment of N-benzyl-N-methylmethanesulfonamide with catalytic Pd(OAc)2 in the presence of sodium tert-butoxide, triphenylphosphine and toluene afforded N-
