Ortho-substituted benzyl esters of cyclopropanecarboxylic acids

Ortho-substituted benzyl esters of cyclopropanecarboxylic acids I STR1 where X is N or CH and A is one of the following cyclopropane radicals: STR2 where R1 is CN, C2 -C8 -alkyl, CF3, C3 -C8 -alkenyl, (C1 -C4 -alkoxycarbonyl, unsubstituted or substituted phenyl-C1 -C6 -alkyl or phenyl-C3 -C6 -alkenyl, ethoxyphenyl, 2- or 3-bromophenyl, 2- or 4-trifluoromethylphenyl, 2,4- or 2,6-difluorophenyl, 2-fluoro-6-chlorophenyl, 2,4- or 2,6-dimethylphenyl, 2,3,6-trichlorophenyl or trimethylsilyl, R2 is H or halogen, R3 is unsubstituted or substituted phenyl, R4 is CH3 or halogen and Hal is halogen, with the proviso that X is CH when R1 is CF3 or trimethylsilyl, are suitable as fungicides and for controlling pests.

Process for cyclizing upsilon-chlorocarboxylic acids

γ-chlorocarboxylic acid methyl or ethyl esters are cyclized to the corresponding cyclopropane carboxylic acid esters by employing the sodium or potassium alcoholate of methanol or ethanol in the presence of the same alcohol at a temperature above the boiling point of the alcohol employed.
