Tonsil Actisil FF, a commercial bentonitic clay, promotes the formation of a series of electrophilic-aromatic-substitution products from para-methoxybenzyl acetate in carbon disulfide. The molecules obtained correspond to linear isomeric dimers, trimers, tetramers and a pentamer, according to their spectroscopic data. A clear indication of the title mechanistic pathway for the oligomerization growth was obtained from the analysis of a set of computational-chemistry calculations using the density-functional-theory level B3LYP/6-311++G(d,p). The corresponding conclusions were based on the computed dipole moments, the HOMO/LUMO distributions, and a natural-populations analysis of the studied molecules.
商业膨润土材料托普尼尔斯粘土FF(Tonsil Actisil FF)促进了对甲氧基苄基乙酸酯在二硫化碳中形成一系列亲电芳香取代产物。通过其光谱数据,所获得的分子对应于线性异构二聚体、三聚体、四聚体和五聚体。利用密度泛函理论B3LYP/6-311++G(d, p)水平的一组计算化学计算分析,得到了寡聚生长机制途径的明确指示。相应的结论基于计算的偶极矩、HOMO/LUMO分布和所研究分子的自然种群分析。
