Versuchsvorschrift

To a solution of 0.688 mole (219 g.) of 2,5-bis(2,2,2-trifluoroethoxy)benzoic acid in 657 ml. of benzene is added 1.376M. (100.4 ml.) of thionyl chloride slowly over 1 hour while heating to about 60° C. The mixture is then heated at reflux for about 8 hours, then evaporated to provide the desired product, 2,5-bis(2,2,2-trifluoroethoxy)benzoic acid chloride as a residue. The structure is verified by means of infrared spectral analysis.
