| Popis: | New quinazolinone-substituted fluoran compounds were synthesized by reaction of keto acid, 2’-carboxy-2-hydroxy-4-N-pyrrolidinylbenzophenone with different quinazolinone derivatives in the presence of conc. sulphuric acid. All the synthesized fluoran compounds were characterized by spectroscopic methods (IR, 1H-NMR and UV-visible spectroscopy) and elemental analysis. The fluoran compounds are colorless or nearly colorless and develop color on contact with electron-accepting compounds. |
