1-(chloromethyl)-2,3,4,5,6-pentafluorobenzene

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 0.1 mole of potassium (±) trans-2,2-dimethyl-3-dichlorovinyl-cyclopropanecarboxylate and 0.1 mole of pentafluorobenzyl chloride were heated in acetonitrile until the reaction was complete. After concentrating, taking up in water/petroleum ether and concentrating the organic phase, a colorless oil was obtained, in the NMR spectrum of which the doublet mentioned in Example 2 for the vinyl proton of the cis-ester was lacking. After concentrating concentrating the organic phase a colorless oil was obtained, in the NMR spectrum of which the doublet
