Abstract
3,5-Dichloro-2,4-difluoroaniline was synthesized from 2,4-difluoronitrobenzene by chlorination and reduction reaction. The 2,6-difluorobenzamide was synthesized from 2,6-dichlorobenzonitrile via fluorination and hydrolysis. An acylation reaction based on 2,6-difluorobenzamide and bis(trichloro-methyl)carbonate was carried out to produce 2,6-difluorobenzoyl isocyanate, afterwards the addition reaction with 3,5-dichloro-2,4-difluoroaniline was conducted to synthesize insecticide Teflubenzuron. The overall yield was 75.3%.
