| Abstract: | 2, 6 - Difluorobenzamide, an intermediate of benzoyl urea pesticides, is synthesized from 2, 6 - dichlorotoluene by ammoxidation, fluorination and hydrolysis in 85. 8 %, 92. 7%, 96.2% yield respectively and in 76. 6% total yield. This route is convenient and practical, having excellent economical index. It will promote the research and production of benzoyl urea pesticides in our country. |
