Converting (E)‐(Hetero)arylethanesulfonyl Fluorides to (Z)‐(Hetero)arylethanesulfonyl Fluorides Under Light Irradiation

The construction of ( Z )‐(hetero)arylethenesulfonyl fluorides was achieved utilizing Iridium photoredox catalysis under UV‐light irradiation. This protocol provided a diverse range of ( Z )‐(hetero)arylethenesulfonyl fluorides in moderate to good yields under mild conditions without external additives. The late‐stage transformation of the ( Z )‐(hetero)arylethenesulfonyl fluorides comparing with their E ‐configuration counterparts was also studied.
