    • Novel carboxylic acid esters represented by the formula,

      WHEREIN R1 represents hydrogen atom or methyl group; R2 represents methyl, 2-methyl-1-propenyl or 2-methoxy-carbonyl-1propenyl group when R1 is hydrogen atom, and R2 represents methyl group when R1 is methyl group; and R represents

      (WHEREIN R3 is a phenylene group, a thiophene residue or a furan residue),

      (WHEREIN R4 is an allyl or propargyl group) or R5-CH2-C*C(CH2)n- (wherein R5 is a phenyl, chlorophenyl, tolyl, thienyl, furyl or ethynyl group, and n is an integer of 1 or 2), which may be useful for the production of insecticides having excellent insecticidal activity and low toxicity to mammals.
    • 由式表示的新型羧酸酯,WHERE R1表示氢原子或甲基; 当R 1是氢原子时,R 2表示甲基,2-甲基-1-丙烯基或2-甲氧基 - 羰基-1-丙烯基,当R 1是甲基时,R 2表示甲基; 并且R表示(其中R 3是亚苯基,噻吩残基或呋喃残基),(其中R 4是烯丙基或炔丙基)或R 5 -CH 2 -C 3 CF(CH 2)n - (其中R 5是苯基 ,氯苯基,甲苯基,噻吩基,呋喃基或乙炔基,n为1或2的整数),其可用于生产具有优异的杀虫活性和对哺乳动物毒性低的杀虫剂。
