Abstract
We are reporting the preparation and use in cross coupling reactions of a newly developed, bench‐stable (1 fluorocyclopropyl)metalloid reagent. The Stille cross coupling reaction described for this α‐fluorinated stannane reagent is amenable to a wide range of aryl and alkenyl (pseudo)halides bearing a variety of functional groups. An enantioenriched cross‐coupled product was also obtained from the corresponding 1‐fluorocyclopropyltin reagent bearing an ester handle. Finally, the chemical stability of the 1 fluorocyclopropyl moiety was also demonstrated by performing several post‐functionalizations.
