Procedure
205.6 g (1.19 mols) of 2,4,4-trichlorobut-3-enecarboxylic acid [produced according to Monateshefte d. Chemie, 98, 2138 (1967)] is heated with 290 ml of thionyl chloride for 5 hours at 85° C. The reaction solution is concentrated by evaporation and subsequently distilled to obtain 209.7 g of 2,4,4-trichlorobut-3-enecarboxylic acid chloride; b.p. 75°-76° C./20 mm Hg. The spectroscopic data of the substance obtained agree with those of the products obtained according to (a).
