Process for preparing 2,2'-dimethyl-1,1'binaphthyl and 2,7'-dimethyl-1,1'-binaphthyl

摘要

2,7'-Dimethyl-1,1'-binaphthyl and a process for preparing 2,2'-dimethyl-1,1'-binaphthyl and 2,7'-dimethyl-1,1'-binaphthyl by electrochemically oxidatively dimerizing 2-methylnaphthalene in the presence of acetonitrile/water/electrolyte salt mixtures which additionally contain at least one further component which, is immiscible or only partially miscible with water, and rectifying the reaction mixture obtained under reduced pressure.
