These common heterocyclic compound, 630-18-2, name is Pivalonitrile, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route. Recommanded Product: 630-18-2
General procedure: To an ice cold solution of pivalonitrile (1f, 120 muL, 1.085 mmol) in Et2O (1.0 mL)was added an ethereal solution of 2-naphthylmagnesium bromide (2b, 0.75 M, 1.88mL, 1.410 mmol) and the reaction mixture was stirred at 60 C in a sealed tube for 2 h.After cooling to 0 C, the reaction mixture was treated with anhydrous MeOH (132muL), followed by the addition of CuBr2 (24.3 mg, 0.109 mmol) and anhydrous DMF(10.0 mL). The resulting reaction mixture was stirred at 80 C under an oxygenatmosphere for 6 h. Then the reaction was quenched by the addition of pH 9ammonium buffer solution and the organic materials were extracted with Et2O. Thecombined organic extracts were washed with water, and then with brine and driedover anhydrous MgSO4. The solvents were removed in vacuo and the resulting crudematerial was purified by flash column chromatography using hexane-EtOAc (90:10)to afford 2-naphthonitrile
The synthetic route of Pivalonitrile has been constantly updated, and we look forward to future research findings.
