Abstract

Mechanistic studies reveal that Pd-catalyzed C(sp³)–H arylation of thioethers with silver(I) additives takes place via C(sp³)–H activation, oxidative addition and reductive elimination, wherein all steps proceed via the heterodimeric Pd–Ag pathway. Besides, the active heterodimeric Pd–Ag species are detected by mass spectrometry via control experiments.
