研究了芳环上取代基诱导效应能和共轭效应能的分离,Ph(X)n的(X)n基属性从能量角度提出量化解释及应用,发现各类芳环取代基都不同程度存在两种σ_c、σ_I效应,且存有群轨道作用。
The separation of the induction and the conjugation effects of the substituents on the aromatic ring was studied. The (X) n radical of Ph (X) n was quantitatively explained and applied from the energy point of view. It was found that various aromatic ring substituents were present to varying degrees Two kinds of σ_c, σ_I effect, and there are group orbital role.
