For the cases studied, different regiochemistries are observed depending on the initial position of the sulfonamide linker.engAtribución-NoComercial 4.0 Internacionalhttp://creativecommons.org/licenses/by-nc/4.0/Ipso-substitutionBiarylsderivativesCyclizationC-H Arylationinfo:eu-repo/semantics/article10.1039/d0ra02026einfo:eu-repo/semantics/openAccess
