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
