Title of the InventionNOVEL 2-ARYLPROPYL ETHER OR THIOETHERDERIVATIVES, PROCESSES FOR PREPARATIONTHEREOF AND INSECTICIDAL AND ACARICIDALAGENTS CONTAINING SAID DERIVATIVESAbstract of the DisclosureThe present invention relates to 2-arylpropyl etheror thioether derivatives represented by the followinggeneral formula [I]:[I]wherein Ar stands for an aryl group, R stands for amethyl or ethyl group, Y stands for an oxygen orsulfur atom, and B stands for a group representedby the following formula [II]: [II]or the following general formula [III]:[III]wherein Z stands for an oxygen or sulfur atom or acarbonyl or methylene group, R1 stands for a hydrogenor halogen atom or a lower alkyl group or a lower- 1 -alkoxy group, and n is an integer of from 1 to 5 withthe proviso that when n is 2 or more, the groups R1may be the same or different,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 -
