METHOD OF SYNTHESIS OF 2,6-DIFLUORO-N-ALKYLBENZENES Russian patent published in 1995 - IPC

Abstract RU 2035447 C1

FIELD: organic chemistry. SUBSTANCE: reagent 1: 1,3-difluorobenzene. Reagent 2: alkyl (methyl, ethyl, n-butyl) chloride. Reaction conditions: alkylation in the presence of sodium amide in liquid ammonia medium. Synthesized 2,6-difluoro-n-alkylbenzenes were used for synthesis of herbicides and insecticides. EFFECT: improved method of synthesis, decreased cost of chloroalkyls.
