Zha, Gao-Feng published the artcilePalladium-Catalyzed Fluorosulfonylvinylation of Organic Iodides, Product Details of C8H5IO, the publication is Angewandte Chemie, International Edition (2017), 56(17), 4849-4852, database is CAplus and MEDLINE.
In the presence of Pd(OAc)2, ethenesulfonyl fluoride underwent chemo-, regio- and diastereoselective aerobic Heck reactions with aryl, heteroaryl, and vinyl iodides mediated by silver trifluoroacetate in acetone to yield arylvinylsulfonyl fluorides such as (E)-PhCH:CHSO2F and (E,E)-PhCH:CHCH:CHSO2F in 24-99% yields. The structure of (E,E)-PhCH:CHCH:CHSO2F was determined by x-ray crystallog.
