Abstract

9‐alkyl‐10‐methylanthracenes can easely be prepared on a large scale and in good yields by the following steps: anthraquinone → anthrone → 9‐alkylanthracene → 9‐alkyl‐10‐formylanthracene → 9‐alkyl‐10‐methylanthracene.

The following hydrocarbons have been obtained by this method: 9‐methyl‐, 9‐ethyl‐, 9‐n.propyl‐, 9‐n.butyl‐, and 9‐n.amyl‐10‐méthyl‐anthracenes.

For the preparation of 9,10‐dimethylantracene, the intermediate 9‐methylanthracene can also be prepared satisfactorily by formylation of anthracene followed by reduction of the formyl group by the Huang‐Minlon modification of the Wolff‐Kishner procedure.
