芳香族取代反應性及位向的探討

The Quantum Mechanical Studies of Substitution-Reaction and Orientation

摘要


分子軌域微擾理論及一次微擾分子軌域理論的方法可用來預估偶數交替芳香族分子的反應位置及分子內取代基對反應性的影響,在進行異性分裂芳香族取代反應時,此簡易半定量告知活性高反應位置的方法,同時也可告訴取代基影響最大的位置,由這些方法預估所得的結果與實驗數據非常吻合。

The PMO method and first order perturbational molecular orbital theory method are used to predict the reaction positions of even alternant aromatic molecules and the effect of the substituent in the molecule. These semiquantitative methods are easy to tell the active site which the heterolytic aromatic substitutions are involved. They also tell the most effective location of the substituents. The results predicted by these methods agree with experimental datum very well.
