Procedure

In a distillation equipment, a mixture of 51 g (0.33 mol) of 2-fluoro-2-chloro-1-methylcyclopropanecarboxylic acid and 60 g (0.5 mol) of thionyl chloride is heated slowly with stirring, during which process excess thionyl chloride distils over first and the desired product later. In this manner, 54 g (97% of theory) of 2-fluoro-2-chloro-1-methylcyclopropanecarbonyl chloride are obtained in the form of a liquid of boiling point 82°-85° C./100 mbar.
