Benzoylation of 4‐methylfluorene according to Friedel ‐ Crafts in carbon disulfide with aluminium chloride yielded two benzoyl derivatives: 5‐methyl‐2‐benzoyl‐fluorene (II) (major product), and 4‐methyl‐2‐benzoyl‐fluorene (III). By oxidation II and III gave the corresponding 9‐oxo‐derivatives, the structure of the last compounds being proved by an independent way.
