Abstract
According to the present invention, two hydroxyl groups can be introduced into the 1-position and the 4-position of the benzene ring of an aromatic compound highly efficiently and highly selectively by a one step process to give the corresponding aromatic hydroxide. The present invention provides a production method of an aromatic hydroxide represented by the formula (2) wherein R, R, R, and, Rare each independently a hydrogen atom or an alkyl group having a carbon atom number of 1-20, and R, Rand/or Rand Rare optionally bonded to each other to form a ring, which comprises irradiating light to a photoelectrode comprised of metal oxide while applying a given potential in the presence of an aromatic compound represented by the formula (1) wherein R, R, R, and Rare as defined above.
