Under the catalysis of chiral Cu(Ⅱ) complex,C2 and C3 alkylation of pyrrole and C3 alkylation of indole were realized simultaneously.The chiral oxindole skeleton with an all-carbon quaternary stereogenic center at the C3-position could be obtained exclusively with high yields (up to 95%) and excellent enantioselectivities (up to > 99%).

本文研究外加电场对离子交联聚乙烯的微观结构和能量特性的影响,使用分子模拟法建立PbO作硫化剂的交联聚乙烯分子模型,通过半经验法对模型进行几何优化同时施加沿X轴方向的外电场,计算离子交联聚乙烯的分子总能量、偶极矩、极化率、分子轨道能量、能隙、红外光谱、电荷分布并进行分析.得出结论:随着外加电场的上升,交联聚乙烯分子结构会发生变化,当外加电场过大时本文所建交联聚乙烯分子离子盐桥的S-Pb-S键将会发生断裂形成自由基.外加电场会使分子内部的电荷从交联聚乙烯碳链端部向离子盐桥转移,盐桥处Pb原子电荷量不断积累,到
超级奥氏体不锈钢中因含有更高铬、钼含量,具有极高的耐点蚀、晶间腐蚀性能,这与Mo等合金元素对钝化膜结构的影响密切相关,尤其含硼超奥钢钝化层表面Cr、Mo含量明显增加,但其原子层次的微观作用机制尚不清楚.本文采用第一性原理方法,研究了置换原子(Mo、Mn、Ni、Si),及间隙原子B在fcc-Fe/Cr2O3界面占位倾向,并分析了可稳定存在于界面B对这些元素偏析倾向的影响.结果表明:Mo、Mn、Ni、Si、B均可与fcc-Fe/Cr2O3界面结构体系形成稳定结构;Mo、Ni倾向分布于界面基体侧,Mo有向氧化层
采用密度泛函理论方法,系统研究了1-乙基-3-甲基咪唑离子([C2 MIM]+)在三种不同管径的碳纳米管中的稳定结构、相互作用能和分子轨道性质.研究表明,随着碳纳米管管径的增加,[C2 MIM]+在碳纳米管内的稳定结构从居中的位置越发靠近碳纳米管的管壁,其与碳纳米管的结合能也从-45.52 kcal/mol降低到-39.45 kcal/mol.通过分析[C2 MIM]+在不同尺寸碳纳米管中的分子轨道排布,发现研究体系的HOMO轨道和LUMO轨道主要是局域在碳纳米管上,电子跃迁表现为π→π?,表明[C2 M

A gold(Ⅰ)-catalyzed 6-endo-dig cyclization of aromatic 1,5-enynes was developed to synthesize 2-(naphthalen-2-yl)anilines.The func-tional group tolerance of this cyclization was examined systematically and a possible mechanism was proposed.The derivatizat
Polyarsenides containing coinage metals,[As7Cu(PPh3)]2-(1) and[M2As14]4-(M =Cu,2;Ag,3),were synthesized by reactions of the nominal composition K3As7 with Group 11 metal complexes.The possible intermediate,cluster 1,was isolated from the solution phase th

Sr2CrBO6(B=Os,Re,W)被证实是具有最高磁转变温度的双钙钛矿氧化物.论文采用基于密度泛函理论的第一性原理方法,计算了Sr2CrBO6的电子结构和光学性质,并通过计算结果分析了二者之间的内在关系.总体来看,B位元素的改变对材料的电子结构和光学性质都产生了较大的影响.由能带结构的计算,Sr2CrOsO6为半导体,Sr2CrReO6和Sr2CrWO6为半金属.晶体介电函数虚部ε2(ω)曲线在所考察的能量范围内存在明显的介电特征峰,论文结合态密度和能带结构讨论了这些介电峰所对应的电子跃迁过程.Sr2
