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. 630-18-2, name is Pivalonitrile belongs to nitriles-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below. Recommanded Product: Pivalonitrile
General procedure: To a solution of 4-bromobiphenyl 1a (3.0 mmol, 699.3 mg) in THF (3.0 mL) was added n-BuLi (4.5 mmol, 1.55 M in hexane, 2.87 mL) at 50 C. The obtained mixture was stirred for 30 min at 50 C under an argon atmosphere. Pivalonitrile (6.0 mmol, 498.8 mg) in THF (2.0 mL) was added to the mixture at 50 C and the obtained mixture was stirred for 30 min in the temperature range of 50 C to room temperature. MeOH (2.0 mL) was added to the mixture. Then, I2 (12.0 mmol, 3045.6 mg) and K2CO3 (12.0 mmol, 1658.4 mg) were added to the mixture at room temperature, and the obtained mixture was stirred for 6 h at 70 C. Sat. aq. Na2SO3 solution (20.0 mL) was added to the reaction mixture, and the product was extracted with AcOEt (10.0 mL x 3). The organic layer was dried over Na2SO4. After filtration and removal of the solvent, the residue was purified by silica-gel column chromatography (chloroform: n-hexane 1:1) to give 4-cyanobiphenyl 2a (451.6 mg, 84%).
The synthetic route of 630-18-2 has been constantly updated, and we look forward to future research findings.
