| Abstract: | Abstract The ir and nmr spectra of 24 3-naphthyl-4-quinazolones were examined. There are three principal ir bands in the 1500 and 1705 cm?1 region of the spectra. The first at 1685–1705 cm?1 is assigned to the tertiary amide carbonyl (ArCONR2), the second at 1593–1645 cm?1 to the anil chromophore (ArN=C-N) and the third to the naphthalene ring at 1600 cm?1. The nmr band assignments are straight forward. |
