Reaction Conditions:
with oxygen;copper(II) nitrate in acetonitrile at 120; under 4500.45 Torr; for 10 h;
Steps:
27 Example 27
In a 15 mL PTFE-lined reactor, 0.5 mmol of 4-methylacetophenone was added.Weigh 0.1 mmol of copper nitrate as a catalyst,And adding 2mL solvent acetonitrile (4-methyl acetophenone concentration is 0.25mol / L),The oxygen pressure is increased to 0.6 MPa, the temperature is raised to 120 ° C, and the reaction is stirred for 10 hours. After the reaction is completed,The product was detected by gas chromatography-mass spectrometry and the product 4-methylbenzoic acid mass spectrum was identical to the standard mass spectrum.The conversion of the substrate by gas chromatography and the yield of the product 4-methylbenzoic acid are shown in Table 1.
