A palladium‐catalyzed fluorosulfonylvinylation reaction of organiciodides is described. Catalytic Pd(OAc)2 with a stoichiometric amount of silver(I) trifluoroacetate enables the coupling process between either an (hetero)aryl or alkenyl iodide with ethenesulfonyl fluoride (ESF). The method is demonstrated in the successful syntheses of eighty‐eight otherwise difficult to access compounds, in up to

(E)‐2‐(hetero)arylethenesulfonyl fluorides and (E,E)‐1,3‐dienylsulfonyl fluorides are bis‐electrophiles and rare members of the sulfonyl fluoride family with limited information being known of their reactivity and synthetic utility. The direct annulation reaction of these 2‐substituted ethenesulfonyl fluorides with medicinally important enolizable pyrazolones and 1,3‐dicarbonyl compounds utilizing catalytic DBU
