Proposed mechanism of photoredox catalytic activation of SF6 by N‐phenylphenothiazine (3) for pentafluorosulfanylation of α‐methyl (1) and α‐phenyl (2) styrene, and addition by fluoride as an internal nucleophile to give 4 and 5 or alcohols (R2‐OH) as external nucleophiles to give products 8 and 9 (shown for R2=Me).
