外文摘要：In order to elucidate the reaction mechanism of ionic liquid-catalyzed CO2 with 2-aminobenzonitrile, [P4442]2[Hy] with two N- sites is designed for the efficient preparation of quinazoline-2,4(1H,3H)-diones. The results show that [Hy]2- can activate 2-aminobenzonitrile by hydrogen bonding with -NH2 in addition to activating CO2, and the key intermediate is revealed. [P4442]2[Hy] can simultaneously activate CO2 and 2-aminobenzonitrile due to the two N- sites. The H-bond site of [Hy]2- with 2-aminobenzonitrile is confirmed to be -NH2, and the key reaction intermediate is proposed and the mechanism is reconsidered.
