摘要

NEW MATERIAL:The compound of formula I [R1 is halomethyl; R1', R2 and R2' are methyl, halogen or halomethyl; R is group of formula II (R3 is H or methyl; R4 is allkyl, propargyl, etc.), group of formula III (R11 is tetrahydrophthalimido or dialkylmaleimido), etc.; provided that R2 and R2' are not methyl at the same time], its optical isomer or geometrical isomer. EXAMPLE:3'-Phenoxyl-alpha'-cyanobenzyl 2,3-dichloro-2,3-ditrifluoromethylcyclopropanecarboxylate. USE:An insecticidal and miticidal agent having broad insecticidal spectrum and low toxicity. It is stable to light, and can be obtained easily and economically. PROCESS:The compound of formula I is prepared by reacting the compound of formula V or its reactive derivative with compound of formula R-OH or its reactive derivative.
