Reaction Conditions:
with N-hydroxyphthalimide;oxygen in acetonitrile at 30; for 3 h;Schlenk technique;
Steps:
9 Example 9: Synthesis of 2-ethylbutyric acid
5 mol% NHPI was added to a 25 mL Schlenk reaction tube, dried under vacuum for 15 minutes, and oxygen was bubbled in an oxygen atmosphere.2 mL of acetonitrile and 1.0 equivalent of 2-ethylbutanal were added in this order, and an oxygen balloon was connected, and a glass stopper was placed on the reaction tube.Into the oil bath, react at 30 ° C for 3 h. After the reaction is completed, it is concentrated under reduced pressure and separated by column chromatography. The eluent is petroleum ether / ethyl acetate /Dichloromethane (v: v: v = 5: 1:1) gave 2-ethylbutyric acid. Yield 88%, light yellow liquid;
