Paragraph 0029-0031, (2020/12/30)
The invention provides a green synthesis method of a benzocyclohexanone compound, and belongs to the technical field of organic synthesis. The method provided by the invention comprises the followingsteps: by taking 4-phenylbutyric acid as a raw material, firstly carrying out reflux reaction with oxalyl chloride in dichloromethane, carrying out vacuum evaporation to dryness to obtain a crude product of the 4-phenylbutyryl chloride compound, then dissolving the crude product in a solvent, adding a metal-doped modified molecular sieve catalyst to start reaction, and stirring the solution at different temperatures to carry out ring closing reaction, thereby obtaining the product; and after the reaction is finished, carrying out suction filtration, solvent washing, column chromatography purification and other operations to obtain the target product benzocyclohexanone compound. The synthesis method disclosed by the invention is environment-friendly in reaction and simple and convenient tooperate, the catalyst can be recycled, and the synthesis method is suitable for green synthesis of the benzocyclohexanone compound.
