in organic, material, and pharmaceutical chemistry. A palladium/norbornene-catalyzed chemoselective ortho thiolation of aryl halides was reported. The selectivity of reductive elimination for C(Ar)–SR bond formation was well controlled by tuning the ancillary ligand in the aryl-NBE palladacycle Pd(IV) intermediate. The reaction showcased good substrate scope: both S-alkyl and S-aryl thiosulfonates
