to a THT! Screening a diverse library of thioether ligands led to the discovery of tetrahydrothiophene (THT) as a highly reactive and selective ligand for Pd‐catalyzed allylicCHoxidation reactions (see scheme). This novel ligand system provides some of the highest reported yields for the formation of (E)‐linear allylic acetates through allylicCH activation chemistry (BQ = 1,4‐benzoquinone).
