2,6-Difluorobenzamide Chemical Properties,Usage,Production

Description

2,6-Difluorobenzamide is a major metabolite of pesticide diflubenzuron and has been quantitated by HPLC/diode-array method.

Description

2,6-Difluorobenzamide is a white powdery crystal, insoluble in water. It can be obtained by hydrolysis of 2,6-difluorobenzonitrile. 2,6-Difluorobenzamide is an important intermediate in the synthesis process of benzoylurea insecticides, which is used to synthesize the next intermediate 2,6-difluorobenzoyl isocyanate, and finally obtain flubolurea, pyruron, fluridin, lice mite urea and other pesticide varieties. It can also be directly used to synthesize pyruron and flubolea. 2,6-Difluorobenzamide can inhibit the bacterial cell division protein FtsZ[1].

Chemical Properties

white to yellowish powder

Uses

2,6-Difluorobenzamide (CAS# 18063-03-1) is a useful building block used in the synthesis of (E)-3-methyleneisoindolin-1-ones via oxidative annulation acrylates. It is also used in the synthesis of pesticide intermediates, which can be used to produce various insecticides such as fluazuron, chlorpyrifos, and pyrethroids.

Preparation

2,6-Difluorobenzamide is obtained by hydrolysis of 2,6-difluorobenzonitrile.

Synthesis

1897-52-5

18063-03-1

General procedure for the synthesis of 2,6-difluorobenzamide from 2,6-difluorobenzonitrile: (1) 100 g (0.72 mol) of 2,6-difluorobenzonitrile was added slowly and dropwise to a mixed solution of 240 g of concentrated sulfuric acid and 24 ml of water at room temperature. The reaction mixture was stirred at 80°C to 85°C for 12 hours. After completion of the reaction, the mixture was slowly poured into 1.2 kg of ice water and stirred continuously for 30 minutes, followed by filtration. The resulting crystals were washed to neutrality with distilled water and finally dried under vacuum at 85°C. The yield was 91.0 g (80.6% yield) with a melting point of 140°C to 141.5°C.

Toxics Screening Level

The Initial Threshold Screening Level (ITSL) for 2,6-Difluorobenzamide is 11 μg/m3 based on an annual averaging time.
