A number of 6(5 H )‐phenanthridinones have been conveniently prepared from 9‐oxofluorenes through the Schmidt reaction. It has been found that all amino and nitro 9‐oxofluorenes thus far tried gave substituted 6(5 H )‐phenanthridinones with the amino or nitro group situated in the benzene ring attached to the nitrogen of the lactam group. UV and IR spectral data are presented for these compounds.
