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

Abstract

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.
