The oxidative condensation reaction of several kinds of aryl methane catalyzed by alkali in organic solvents was studied and the reaction products were characterized. The results showed that the electron-withdrawing effect of arylmethane substituents affected the activity of oxidative condensation and the structural characteristics of the products. The more electronegative substituents were, the more the electron-withdrawing groups were and the easier the oxidative condensation occurred.
