Abstract: | Benzoylation and acetylation of 1-methylfluorene according Friedel-Crafts in carbon disulfide with aluminium chloride yielded the corresponding 2-acyl derivatives. By oxydation the benzoyl derivative gave 2-benzoyl-9-oxo-fluorene-1-carboxylic acid, cyclizable into 1,2-phthalyl-fluorenone. |
