4-Carboxybenzeneacetic acid

General procedure: The synthesis method of the present application can be used for synthesizing aromatic fatty acids, using carbon dioxide as a carbon source (control pressure is 2-4 MPa), Using zinc powder and lithium chloride as catalysts (the molar amount added is 3 times that of halogenated hydrocarbons), The halogenated hydrocarbon was used as a raw material (addition amount was 8.72 mmol), 2.8 ml of solvent DMF was added per mmol of halogenated hydrocarbon, and the reaction was adjusted at 40-45 C for 16 hours.Part B: The above nitrile ester was stirred with 120 mL of 6 N aq. HCl for 18 h at reflux and then cooled. The mixture was diluted with 160 mL water and then filtered. The white solid was rinsed with water, air-dried briefly, and placed in a vacuum oven at 75 C. for 1 h. This affords 6.89 g (100%) of 4-(carboxy)phenylacetic acid. 1H NMR (300 MHz, DMSO) delta7.92(d, 2H, J=8.5 Hz); 7.49(d, 2H, J=8.4 Hz); 3.63(s, 2H).Part B: The above nitrile ester was stirred with 120 mL of 6 N aq.
