Abstract

A convenient, mild, one-pot synthesis of substituted dibenzo [a, d] cycloheptenes involving the action of ClCH 2 OMe and TiCl 4 on a variety of diphenylethanes,† which incorporates chloromethylation of a hydrocarbon followed by a Friedel–Crafts intramolecular cyclization reaction, is described.
