ABSTRACT:
A method for producing dihydroxybenzophenones by the electrocatalytic oxidation of bis(4-hydroxyphenyl) methanes, or the quinone methide intermediate, with 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (DDQ). Spent oxidant, in the form of DDQH.sub.2, may be recycled and electrochemically regenerated to active DDQ oxidant.
