A Facile Synthesis of Fluorochlorobromoacetic Acid

Article abstract of DOI:10.1007/BF00810292

Fluorochlorobromoacetic acid was synthesized in the sequence of four steps from 1,1,2-trifluoro-2-chloroethylene in an overall yield of approximately 25percent. 1,1,2-Trifluoro-2-chloroethylene was first allowed to react with sodium methoxide to form 1,2-difluoro-1-chloro-2-methoxyethylene, which was then brominated with elemental bromine and the reaction product treated with concentrated sulfuric acid to give methyl fluorochlorobromoacetate.This compound was hydrolized with a diluted sodium hydroxide solution to fluorochlorobromoacetic acid.
