摘    要:采用密度泛函B3LYP/6-311G**方法研究了2-硅萘作为亲二烯体与2,3-二甲基丁二烯的杂Diels-Alder反应的微观机理、势能剖面、取代基效应及溶剂效应,并与硅苯参与的类似反应进行了比较.计算结果表明,所研究反应均以协同非同步的方式进行,且C-Si键总是先于C-C键形成.发生在C1-Si2位上的反应中两个新...

关 键 词:2-硅萘  2,3-二甲基丁二烯  杂Diels-Alder反应  反应机理  密度泛函理论

Abstract:Density functional theory(DFT)-B3LYP/6-311G** method was used to study the mechanism,potential energy surface,substituent effect and solvent effect of hetero-Diels-Alder reactions of 2-silanaphthalenes as dienophiles with 2,3-dimethyl-butadiene,and the obtained results were compared with those of silabenzenes studied previously.The results show that all of studied reactions proceed in a concerted but nonsynchronous way and the formations of C-Si bond always keep ahead the formation of C-C bond.The reactions...
