Palladium(II)‐catalyzed meta‐C−Harylation and alkylation of benzylsulfonamide using 2‐carbomethoxynorbornene (NBE‐CO2Me) as a transient mediator are realized by using a newly developed electron‐deficient directing group and isoquinoline as a ligand. This protocol features broad substrate scope and excellent functional‐group tolerance. The meta‐substituted benyzlsulfonamides can be readily transformed
