Abstract Five derivatives of 2-phenyl-1H-indene-1-one have been prepared and fully characterized. Spectroscopic techniques such as FT-IR, 1H NMR, mass spectrometry, and elemental analysis were used to investigate the chemical structures and physical properties of the prepared compounds. The optimized structures and the distribution of the frontier molecular orbital were obtained using density functional
Upon heating to above their melting temperatures, 3-arylamino-2-phenyl-1H-inden-1-ones and 2,2'-diphenyl-3,3'-bis(arylimino)[2,2'-biindan]-1,1'-dione undergo a skeletal rearrangement to afford N-arylphthalimides along with benzoic acid in the presence of atmospheric oxygen. The photoreaction of these compounds in acetonitrile also results in the formation of these products. The mechanism of the reactions, including the formation of a peroxyl radical followed by its conversion to a nitrogen-centered radical, is proposed.
