<p>NEW MATERIAL:A 2-arylethyl ether derivative and thioether derivative shown by the formula I (Ar is aryl; X1 and X2 are H, or halogen; X3 and X4 are H, halogen, or methyl; n is 1-4; Y is O or S; Z is N, -CH=; R1 and R2 are H, halogen, lower alkyl, or lower alkoxy). EXAMPLE:3-Phenoxybenzyl 1-(4-chlorophenyl)-1-cyclobutylmethyl ether. USE:Useful as an insecticide and acaricide. Effective for controlling sanitary noxious insects such as flies, mosquitoes, cockroaches, etc., agricultural noxious insects such as leaf-hoppers, insects belonging to the family Deltocephalidae, etc., noxious insects living in grain, such as acarids, etc., noxious insects living in animal such as lice, ticks, etc., having low toxicity to men, beasts, and fishes. PROCESS:A compound shown by the formula II is reacted with a compound shown by the formula III [one group of A and B is halogen, and the other is Y-M group (M is H, etc.) or both are hydroxyl], to give a compound shown by the formula I .</p> |
