Application

  • Phenylacetic acid can be used to synthesize a variety of phenyl substituted compounds by Pd (II)-catalyzed C-H activation/aryl-aryl coupling reaction.
  • It can be employed in the preparation of Mn16 single-molecule magnets by reductive aggregation route.
  • It can be used as a precursor to synthesize chromones, isoflavones, and homoisoflavones.
  • It can also be used as a key precursor in the synthesis of emethallicin E and (−)-incarviatone A.
