Acetylation of anthracene by the Friedel‐crafts reaction using chloroform as the solvent

The acetylation of anthracene by the Friedel-Crafts reaction using nitrobenzene as the solvent leads, under certain conditions to pronounced 2-substitution. It is liable to the effect of different factors. No diacetylation occurs. 2-Acetylanthracene is also formed by the isomerisat ion of 9-acetylanthracene. The effect of the solvent and the different factors are discussed. The preparation of 2-acetylanthracene, 2-acetylanthraquinone and anthraquinone-2carboxylic acid are described.

Acetylation of anthracene by the Friedel-Crafts Reaction using ethylene chloride as the solvent leads to a high yield of 1-acetylanthracene. Diacetylation gives a mixture of 1,s-and 1,s-diacetylanthtacene. Oxidation to the corresponding acetylanthraquinones and carboxylic acids is described. IntroductionThe authors i n a previous publication 1 described the acetylation of anthracene using chloroform as the solvent. This, publication deals with the reaction in another solvent, ethylene chloride, which, although resembling chloroform in many respects, showed a different orienting effect.
