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. [ABSTRACT FROM AUTHOR]
