摘要:
The invention relates to a process for preparing 4,4'-dimethyl-1,1'-binaphthyl, by electrochemically oxidatively dimerizing 1-methylnaphthalene in the presence of acetonitrile/water/conducting salt mixtures which additionally contain at least one further component which is immiscible or only partially miscible with water.
