3,5-Dinitrobenzonitrile Usage And Synthesis

Chemical Properties

yellow crystals or crystalline powder

Preparation

In a well-ventilated hood, diphosgene (2 mL) was added dropwise to a cold (0–5 C°), stirred solution of 3,5-dinitrobenzamide (2.1 g, 10 mmol) in trimethyl phosphate (6.3 mL). The reaction mixture was then slowly heated to 60 C° for 5 min to ensure completion of the reaction and also to distil off any generated phosgene. After cooling in an ice/water bath, the reaction mixture was vigorously stirred and iced water (10 mL) was added to destroy any traces of phosgene or chloroformate. The precipitated solid product was collected by filtration, washed with water to eliminate traces of HCl and trimethyl phosphate, and air-dried; yield: 1.88 g (96%), mp 127–129 C°. Recrystallization from diisopropyl ether gave an analytically pure product, mp 130–131 C°.
The same authors also reported that alkyl, benzylic, aryl, and heteroaryl aldoximes bearing various functionalities could be readily converted to the corresponding nitriles using diphosgene in good yields of 82–96%.
