| titleOfInvention | Preparation method of aryl propionic acid compound |
| abstract | The invention provides a preparation method of an aryl propionic acid compound, which comprises the following steps: performing acetylation reaction on the substituted aryl benzene to obtain aryl acetophenone; carrying out hydrogenation reduction reaction on the alpha-substituted aryl ethanone to obtain alpha-substituted aryl ethanol; and in an acid solution, introducing carbon monoxide gas into the alpha-substituted aryl ethanol, and carrying out carbonylation reaction under the combined catalysis of a main catalyst and a cocatalyst to obtain the aryl propionic acid compound, wherein the cocatalyst has the following structural formula: R 1 is one of hydrogen and substituted carboxylic acid group; r 2 Is hydrogen, halogen, substituted or unsubstituted C1-C12 alkyl, substituted or unsubstituted C1-C6 alkoxy, substituted or unsubstitutedOne of substituted C3-C12 cycloalkyl, substituted carbonyl containing C6-C24 aryl or substituted aryl, substituted carbonyl containing C3-C12 heterocyclic group or substituted heterocyclic group, phenyl, substituted phenyl, naphthyl and substituted naphthyl. |
