Notes:
Friedel-Crafts acetylation of phenanthrene (1a) in sym-tetrachloroethane yields mixtures of 2-, 3- and 9-acetylphenanthrenes (2a, 3a, 4). The distribution of isomers is found to depend strongly upon the method of mixing the reagents. Acetylation of 9-chlorophenanthrene (1b), performed by a variety of methods and solvents, led mainly to 3-acetyl-9-chlorophenanthrene (3b) (≥85%). Previously unreported 2-acetyl-9-chlorophenanthrene (2b) was found to form up to a maximum 11% in nitrobenzene.
