CAS 725-05-3: 4'-Methoxybiphenyl-3-carboxylic acid

4'-Methoxy-biphenyl-3-carboxylic acid is a chemical compound that is used in organic synthesis. It can be synthesized from phenol and the aryl bromide. The reaction sequence involves two catalytic steps: an oxidative coupling of the phenol to 4'-methoxy-biphenyl-3-carboxylic acid and then a reductive coupling of furylacetic acid to biphenyl. This product has been shown to have high catalytic activity, which is due to its ability to regenerate the palladium catalyst used in the first step of the reaction sequence. It can be reused many times before it loses its catalytic activity.
