摘要:
2-METHYL-5-(2-PROPYNYL)-3-FURYLMETHYL 2,2,3,3-TETRAMETHYLCYCLOPROPANECARBOXYLATE AND 2-METHYL-5-(2-PROPYNYL)-3-FURYLMETHYL CHRYSANTHEMATE ARE USEFUL PEST CONTROL AGENTS, E.G. AGAINST FLIES, MITES, COCKROACHES, BETTLES, MOTHS, ETC.
摘要:
5-BENZYL-3-FURANMETHANOL, A USEFUL INTERMEDIATE FOR PRODUCING INSECTICIDES OF LOW MAMMALIAN TOXICITY, IS PREPARED BY HEATING AT ABOUT 100*C. AND IN THE PRESENCE OF A HYDROLYZING AGENT AN ACETYLENE COMPOUND OF THE FORMULAE:
C6H5-C*C-CH2-C(-CH2-X)2-OH OR C6H5-CH2-C*C-C(-CH2-X)2-OH
WHEREIN X IS-OH OR A GROUP HYDROLYZABLE TO-OH. WHERE X IS CHLORINE, I IS DERIVED BY REACTING
C6H5C$C-M
WITH
2,2-DI(CL-CH2-)OXIRANE
WHILE II IS DERIVED FROM C6H5CH2C$CM AND CO(CHX) WHERE M REPRESENTS AN ALKALI METAL OR MG HALIDE.
摘要:
5-(2-METHOXYETHYL)FURFURYL CHRYSANTHEMATE SHOWS A STRONGER INSECTICIDAL ACTIVITY THAN ALLETHRIN AND AS LOW A MAMMALIAN TOXICITY AS NATURALLY OCCURRING PYRETHRINS, AND IS USEFUL IN COMBATING A VARIETY OF INSECTS INCLUDES COMMON HOUSEFLIES (MUSCA DOMESTICA).
