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.
