Synthetic Route of 3215-64-3, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 3215-64-3, name is 2-(2,6-Dichlorophenyl)acetonitrile belongs to nitriles-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below.
General procedure: A mixture of 15.3 g (100 mmol) of 2-(2,6difluorophenyl)acetonitrile, 152.5 g (70 mL, 812 mmol) of dibromoethane, and 32.7 g (144 mmol) of Et3BnN+Cl- was isolated from moisture and carbon dioxide and vigorously stirred at 60. A solution prepared from 95 g (1430 mmol, ?84.5%) of KOH and 95 mL of water was then added dropwise; the mixture was stirred during 6 h at 60-65C, and left overnight. On the next day, the reaction mixture was extracted with t-BuOMe (3×100 mL), the combined organic fractions were evaporated, and residual water was removed via azeotropic distillation with toluene. Then 60 mL of water and 40 mL of concentrated sulfuric acid were added to the obtained 1-(2,6-difluorophenyl)cyclopropanecarbonitrile, and the mixture was refluxed during 4 h. The reaction mass was cooled to ambient; the precipitate was filtered off and dried. Yield 17.82 g (90%), mp 156-157 (toluene).
The synthetic route of 2-(2,6-Dichlorophenyl)acetonitrile has been constantly updated, and we look forward to future research findings.
