Abstract
Elaboration of 2-fluoro-α,β,β-trifluorostyrene 7, prepared by the palladium catalyzed coupling reaction of l-fluoro-2-iodobenzene with a trifluorovinylzinc reagent, yielded the trifluorovinyl-containing imide 1. Thermal dimerization of 1 at 140-160°C leads predominately to the corresponding E-cyclobutane 12, whose structure was established by x-ray crystallography. Similar methodology was utilized to prepare 2,2-bis{4-[4-amino-2-(l,2,2-trifluoroethenyl)phenoxy]phenyl)hexafluoropropane 19, a precursor to the trifluorovinyl-containing polyimide 18.
