| description | The invention relates to a method for efficiently catalytically converting carbon dioxide into quinazoline diketone compounds by using a deep eutectic solvent under room temperature and atmospheric pressure conditions. According to the method, the deep eutectic solvent synthesized by adopting carbon dioxide and o-aminobenzonitrile with different substituent groups as raw materials, adopting ethylene glycol as a hydrogen bond donor, and adopting 1,5-diazabicyclo[4.3.0] non-5-ene (DBN) as a hydrogen bond acceptor, with the molar ratio of the hydrogen bond donor to the hydrogen bond receptor being 1:4, 1:1 and 4:1 is adopted as a catalyst, and the quinazoline diketone compound is synthesized at room temperature under atmospheric pressure for 1-24 h with the ratio of the substrate dosage to the catalyst dosage being 0.4: 3, 0.7: 3 and 1: 3. The invention provides the method for efficiently catalytically converting carbon dioxide into quinazoline diketone compounds by using the eutectic solvent under the condition |
