Abstract
When 1-halogeno-3-alkene-2-ol is reacted with an ortho-carboxylic ester and/or a ketene acetal, a .gamma.-halogeno-.delta.-unsaturated-carboxylic ester is obtained as a main reaction product. When this intermediate is treated with a basic substance, a substituted cyclopropane-carboxylic ester is formed. This ester can be used as an insecticide or an agricultural chemical as it is or after the alcohol residue of the ester has been converted to other alcohol residue.
