Abstract (en)
[origin: WO8201003A1] Compounds are prepared corresponding to the formula (FORMULA) wherein Y represents chloro or R'; R represents (FORMULA) wherein X independently represents alkyl of 1 to 4 carbon atoms, alkoxy of 1 to 4 carbon atoms, alkylthio of 1 to 4 carbon atoms, alkyl sulfonyl of 1 to 4 carbon atoms, trifluoromethyl, chloro, fluoro or bromo; n represents an integer of 0 to 2 or X<un>u represents 3, 4-methylenedioxy and R' represents R with the proviso that R and R' can be the same or different. The compounds are useful as intermediates for the preparation of insecticidal substituted pyridine methyl esters of cyclopropane carboxylic acids.
