Embodiment 1
[0014] Add dry o-chlorophenol and methanol solvent and chemically pure α-pinene reactant to the autoclave filled with carbon monoxide gas, wherein the volume ratio of o-chlorophenol and methanol is 10:1, pinene and solvent o-chloro The volume ratio of phenol and methanol is: 4:1, and add palladium chloride, 2,2'-dipyridyl, p-benzoquinone, trifluoromethanesulfonic acid to form the catalytic system, wherein the molar concentration of palladium chloride is 1 ×10 -3 mol / L, the molar concentration of 2,2'-bipyridine is 5×10 -3 , the molar concentration of p-benzoquinone is: 1×10 -3 mol / L, the molar concentration of trifluoromethanesulfonic acid is: 2×10 -4 mol / L. Ventilate 3 times with carbon monoxide gas at room temperature. Then pressurize the carbon monoxide to 2 MPa, turn on the temperature controller, rapidly raise the temperature to 30°C, record the time, and stop the reaction after 1 hour of reaction. After the reaction was completed, cool to room temperature, release t...
