provides a practical high yield route to α,β,β- trifluorostyrenes. Ortho, meta, and para substituted aryl iodides all work equally well. Similar coupling with - and -1-iodo--propenes outlines the first stereospecific preparative route to 1-aryl--olefins. This approach provides a rapid, easily scaled-up synthesis a one pot procedure to these valuable styrenes from commercially available precursors without

Fluor‐ing it: The stable, crystalline trimethoxy(trifluorovinyl)borate is a convenient reagent for efficiently displacing a bromineatom with a trifluorovinyl group (see scheme). This Suzuki coupling reaction significantly simplifies the route to trifluorostyrenes, which might be interesting compounds for materials science or medicinal chemistry.
