Fluoranthene studies. III. A synthesis of 3-bromo-6-nitrofluorenone

Abstract

A synthesis of 3-bromo-6-nitrofluorenone has been accomplished by the diazotization and Pschorr cyclization of 2-amino-4-bromo-4′-nitrobenzophenone, the synthesis of which is described. The identity of the above bromonitrofluorenone with the degradative oxidation product of 9-bromo-2-nitrofluoranthene establishes unequivocally the structure of the latter substance.
