実験手順
A disadvantage here is the high reaction temperature needed, the unsatisfactory yield and the difficult accessibility of the compounds of the formula (I). Monatshefte der Chemie 90, 680 (1959) describes the reaction of 2,4-difluorobenzaldehyde with acetic anhydride at 180° C., 2,4-difluoro-cinnamic acid being obtained in a 77% yield.
