采用G3B3//B3LYP/6-311++G(d,p)方法研究了HNCX(X=O,S)与F原子的反应机理.找到了六条可能的反应通道,计算结果表明,该反应的主产物为HF+NCX(X=O,S).对反应过程进行了电子密度拓扑分析,讨论了反应过程中化学键的断裂和生成规律,找到了HNCX(X=O,S)和F反应过程中的T型结构过渡态、三元环状结构过渡区和四元环状结构过渡区.
Six possible reaction channels for the reaction of HNCX(X=O,S) and F have been studied at the G3B3//B3LYP/6-311++G(d,p) levels.The breakage and formation of the chemical bonds in the reac-tions have been discussed by the topological analysis method of electronic density,and the T-shaped struc-ture transition states and ring-shaped structure transition regions have been found in the reactions.
