Thionyl Chloride → HCID 53680508, compound

Participants

Reaction Steps

8.7 g (0.0365 mol) of 2,2-dimethyl-3-(3,3,3-trifluoro-2-methoxy-prop-1-enyl)-cyclopropanecarboxylic acid were dissolved in 100 ml of carbon tetrachloride, and 21 g of thionyl chloride were slowly added dropwise at 60° C., while stirring. The mixture was then heated to the reflux temperature for 4 hours. After this reaction time, excess thionyl chloride and carbon tetrachloride were distilled off under a waterpump vacuum. The residue was distilled in vacuo. 6 g (64.2% of theory) of 2,2-dimethyl-3-(3,3,3-trifluoro-2-methoxy-prop-1-enyl)-cyclopropanecarboxylic acid chloride were obtained as a slightly yellow liquid with a boiling point of 80° C./2 mbar.
