摘要

Abstract of the DisclosureThe present invention relates to 2-arylethyl etheror thioether derivatives represented by the followinggeneral formula [I] : [I]wherein Ar stands for an aryl group, R1 stands forstraight or branched chain alkyl group of 1 to 6carbons, R2 stands for a hydrogen atom, or a methylor ethyl group, R3 stands for a halogen atom, ora methyl or methoxyl group, R4 stands for a hydrogenor halogen atom, or a lower alkyl or lower alkoxygroup, and n is an integer of 1 or 2 with the provisothat when n is 2, the groups R4 may be the same ordifferent, and Y stands for an oxygen or sulfur atom,- 1 -and also to processes for the preparation of these ethers orthioethers and a use of these ethers or thioethers.These compounds of the present invention have excellentinsecticidal and acaricidal activities while the toxicity ofthese compounds are very low.- 2 -
