Synthesis, purification and spectral analysis of mononitrocyclopenta[<i>cd</i>]pyrenes

Abstract

Abstract The synthesis, purification and characterization of seven isomeric nitrocyclopenta[ cd ]‐pyrenes (nitroCPPs) are described. Nitration of partially hydrogenated CPPs affords mixtures of nitro derivatives, which, after separation, are aromatized with DDQ. The resulting nitroCPPs are characterized by their 1 H NMR, 13 C NMR, UV‐vis, IR and mass spectra. The interaction between the nitro group and the aromatic system of CPP is discussed.
