Pyridine → trans-3-[(4-Fluorophenyl)methyl]-1-indanyl cis-3-(2,2-dichloroethenyl)-2,2-dimethylcyclopropanecarboxylate

Participants

Reaction Steps

In the manner of Example 4, the reaction of 1.00 g (0.004 mole) of trans-3-[(4-fluorophenyl)methyl]-1-indanol (96% trans, 4% cis) and 0.93 (0.004 mole) of cis-3-(2,2-dichloroethenyl)-2,2-dimethylcyclopropanecarbonyl chloride in the presence of 0.32 g (0.004 mole) of pyridine and 50 mL of toluene gave 1.42 g of trans-3-[(4-fluorophenyl)methyl]-1-indanyl cis-3-(2,2-dichloroethenyl)-2,2-dimethylcyclopropanecarboxylate. The ir and nmr spectra were consistent with the proposed structure.
