利用实验和理论电荷密度分析对六个四旋风进行了系统的研究。基于分子原子量子理论(QTAIM)、核无关化学位移(NICS)准则和源函数(SF)贡献,采用三管齐下的方法确定了所有衍生物中中心五元环的抗芳性程度。在等密度表面绘制的静电电位图表明,吸电子取代基在保持极性方向的同时使羰基的C和O原子的电正性增强。
A systematic study of six tetracyclones has been carried out using experimental and theoretical charge density analysis. A three pronged approach based on quantum theory of atoms in molecules (QTAIM), nucleus independent chemical shifts (NICS) criterion, and source function (SF) contributions has been performed to establish the degree of antiaromaticity of the central five-membered ring in all the derivatives. Electrostatic potentials mapped on the isodensity surface show that electron withdrawing substituents turn both C and O atoms of the carbonyl group more electropositive while retaining the direction of polarity.
