几种含氧杂环化合物的芳香性:一个理论研究
Aromatic effect on some oxo heterocyclic compounds: a theoretical investigation
【摘要】 使用Gaussian94程序包,在B3LYP/6-311++G**基组水平上对2,3-二氢呋喃、2,5-二氢呋喃四氢呋喃、1,3-二氧杂环戊二烯和苯并1,3-二氧杂环戊二烯进行了全优化,并应用结构分析、振动模式分析和电子布居分析对主题化合物进行了充分讨论。应用电子布居分析,得到了芳香性顺序:THF>BDO>2,3-二氢呋喃>1,3-二氧杂环戊二烯>2,5-二氢呋喃。而且,运用TAC的电子布居分析是研究分子结构和芳香性的一种好方法。
【Abstract】 2, 3-dihydrofuran, 2, 5-dihydrofuran, THF, 1, 3-dioxole and 1, 3-benzodioxole are fully optimized with Gaussian94 program package at B3LYP/6-311 ++G** level. The aromatic effect of the title compounds is discussed extensively using structural analysis, vibrational mode analysis and electron population analysis. Then the order of aromatic effect of THF > BDO> 2, 3-dihydrofuran > 1,3-dioxole > 2,5-dihydrofiiran is obtained using total atomic charges. Moreover, electron population analysis with TAC is a good method to investigate molecular geometries and aromatic effect.
【Key words】 aromatic effect; vibrational mode analysis; electron population analysis;
