NEW MATERIAL:The compound of formula I (R1 is lower alkyl, lower alkoxy, lower alkenyloxy, etc.; R2 is H or halogen; R3 and R4 are CH3 or R3 and R4 together form ethylene or 1,1-difluoroethylene; R5 is lower alkyl, lower alkenyl, lower alkynyl, etc.; R6 is H or F). EXAMPLE:4-Methyl-4-(4-ethoxyphenyl)-1-(3-phenoxyphenyl)penthyl ethyl ether. USE:Insecticidal and miticidal agent. It has no residual property in environment in contrast with organic chlorine insecticide and relatively low toxicity to man, animal and fish, and exhibits remarkable effect against vermin resistant to organo-phosphoric pesticides and carbamate pesticides. PREPARATION:The compound of formula I can be produced by converting the unsaturated carbinol of formula II to the compound of formula III by cata lytic reduction, and reacting the resultant compound with the compound of formula R5-X (X is halogen, tosyloxy or mesyloxy) in the presence of a base.
