摘要
采用B3LYP/6-311G方法,对氨力农分子的烯醇式构型作构象分析。再采用相同方法计算并考察烯醇式与酮式结构互变时质子迁移的2种可能途径:(a)分子内质子迁移,(b)水助质子迁移。结果表明,b所需的活化能较小,氢键在降低反应活化能方面起着重要作用。
The processes of proton transfer between the keto tautomer and the enol tautomer of amrinone were investigated by density functional theory at B3LYP/6-311 G^* * level. The two possible reaction pathways:(a) intramolecular proton transfer; (b) water-assisted intermolecular transfer were investigated. The calculated results showed that the processes (b) has lower activation energies. It is likely that the hydrogen bonds formed in the complexes play an important role in proton transfer process in the later reaction pathway.
