摘要
用AM1方法优化了二溴卡宾与对 甲基苯乙酮环加成反应的反应物、过渡态、中间体和产物的构型 ,找到了反应的过渡态 ,从理论上论证了二溴卡宾与对 甲基苯乙酮环加成反应的机理 ,得出了该反应为强放热反应 。
AM1 method has been employed to study the reaction pathway and to optimize structures of the reactant, product, intermediate and transition state for the cycle addition reaction of dibromo carbene with P methylacetophenone. The reaction mechanism has been determined by the theory. The result shows that the reaction is exothermic reaction, and the second step reaction is control procedure.
