Electric Literature of 134450-56-9, Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 134450-56-9, name is 4,5-Difluorophthalonitrile, This compound has unique chemical properties. The synthetic route is as follows.
Synthesis of compound of formula XVIII is illustrated in Scheme 3 below. (0146) Reaction of 0.5 molar equivalents of carbazole with 4,5-difluorophthalonitrile affords compound 8 which is then reacted with 4 to provide intermediate 9. Hydrolysis of the nitrile functions provides dicarboxylic acid 10 on acidification. Methylation with iodomethane and anion metathesis with saturated NH4PF6 solution provides the product XVIII.
The chemical industry reduces the impact on the environment during synthesis 4,5-Difluorophthalonitrile. I believe this compound will play a more active role in future production and life.
