9,10-Dimethylanthracene

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 1-Phenylindene and the like are prepared from (o-ethylphenyl)phenylmethane. 1-Phenylnaphthalene (boiling point: 324-325° C.), 9,10-dimethylanthracene (melting point: 182-184° C.), and 9-methylanthracene obtained by elimination of a methyl group of 9,10-dimethylanthracene, anthracene (melting point: 216-218° C., boiling point: 342° C.) and the like are prepared from 1-(o-ethylphenyl)-1-phenylethane.

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 9,10-Dihydro-9,10-dimethylanthracene was prepared by hydrogenation of 9,10-dimethylanthracene with Girdler G-22 copper chromite catalyst in toluene at 120° C. and 1500 psi for 1 hour. The mixtures resulting from five such runs were combined and filtered, and the off-white solid product was isolated by evaporating the solvent. It was characterized by nmr spectroscopy. The mixtures resulting from five such runs filtered the off-white solid product was isolated by evaporating the solvent
