| Product | (+/-) trans-2,2-Dimethyl-3-dichlorovinyl-cyclopropanecarboxylic acid pentafluorobenzyl ester | HCID 53392 | — |
Reaction Steps
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.
