Fluoroallene and 1, 3-difluoroallene are prepared in good overall yield by the addition of dichlorocarbene to vinyl fluoride and 1, 2-difluoroethylene respectively, followed by pyrolysis of the dichlorocyclopropanes and treatment of the resulting dichloropropenes with zinc. Pyrolysis of 1, 1-dichloro-2-fluorocyclopropane over zinc gives fluoroallene directly.

Enantioselect‐DeFluor: Carbon–fluorinebond cleavage by a chiral zirconium complex allows the synthesis of optically active 1,3‐difluoroallene for the first time. Its absolute configuration was established by gas‐phase vibrational circular dichroism spectroscopy (see picture).
