The Diels–Alderreaction of trifluorovinyl substances with various dienes proceeded well to give the corresponding trifluorinated cyclohexene derivatives in a regiospecific manner, while 2,3-difluorobuta-1,3-diene molecules also underwent a smooth Diels–Alderreaction with various dienophiles to afford the corresponding vic-difluorocyclohexene structure.
An Effective Preparation of Sulfonyl- or Sulfinyl-Substituted Fluorinated Alkenes and their Stereoselective Addition-Elimination Reactions with Organocuprates
pentafluoropropen‐1‐yl sulfone or sulfoxide, which are easily prepared from commercially available 1,2‐dibromofluoroalkanes, with various organocuprates affords substitution or β‐reduction products in good to excellent yields through an addition–eliminationreaction sequence.
