Abstractβ‐Substituted α‐fluoro‐α,β‐unsaturated carboxylic acids have been successfully synthesized, usually in a (Z)‐stereospecific manner by way of a stepwise or a one‐pot three‐step procedure starting from 2‐chloro‐1,1,1,2‐tetrafluoroethane (HCFC‐124), one of the major byproducts of the industrial process for tetrafluoroethene formation from chlorofluoromethane (HCFC‐22).
