Room temperature preparation of trifluoroethenylzinc reagent by metalation of the readily available halocarbon HFC-134a and an efficient, economically viable synthesis of 1,2,2-trifluorostyrenes

Trifluoroethenylzinc reagent [CF2=CFZnX] was generated from the readily available halocarbon HFC-134a by an in situ metalation-transmetalation procedure at temperatures near to room temperature (15-20 °C). By systematic standardization of the m
PALLADIUM CATALYZED COUPLING OF F-VINYL ZINC REAGENTS WITH ARYL IODIDES. AN IMPROVED SYNTHESIS OF α,β,β-TRIFLUOROSTYRENES AND THE STEREOSPECIFIC PREPARATION OF 1-PHENYL-F-PROPENES

Palladium catalyzed coupling of trifluorovinyl zinc reagents with substituted aryl iodides provides a practical high yield route to α,β,β-trifluororstyrenes.Ortho, meta, and para substituted aryl iodides all work equally well.Similar coupling with E- and Z-1-iodo-F-propenes outlines the first stereospecific preparative route to 1-aryl-F-olefins.This approach provides a rapid, easily scaled-up synthesis via a one pot procedure to these valuable styrenes from commercially available precursors without recourse to low temperature processes or the use of unstable reaction intermediates.
