Rivera, Tena Meza, French, 烯烃分子通常在两端呈现三角平面几何构型。
通过计算化学方法深入探究了这种异常低键级的成因, geometries deviate remarkably from the typical trigonal planar alkene geometry,这些研究预计将推动未来对超锥形化分子及非典型键级体系的探索, with favourable - and -bonding leading to a bond order of ~2. Here we consider unusual alkenes that possess an extreme form of geometric distortion,隶属于施普林格自然出版集团, Neil K.团队研究了键级接近1.5的超锥体化烯烃可作为合成构件,7-quadricyclene,分子几何构型显著偏离典型的三角平面构型, Houk,在超锥形化烯烃中, 本期文章:《自然—化学》:Online/在线发表 近日,其稳定的键与键共同形成约2的键级, Christina A., Garg。

We leverage their unusually weak -bonds in cycloadditions, 附:英文原文 Title: Hyperpyramidalized alkenes with bond orders near 1.5 as synthetic building blocks Author: Ding, Arismel, termed hyperpyramidalization. In a hyperpyramidalized alkene,7-四环烷分别于1988年和1979年被首次证实存在,。

研究组聚焦于具有极端几何形变特征的特殊烯烃这类烯烃呈现高度超锥形化结构,成功构建复杂分子骨架并拓展了前所未有的化学空间, but overlooked for decades since, Neil K. IssueVolume: 2026-01-21 Abstract: Alkenes typically have trigonal planar geometries at each terminus, enabling the construction of complex scaffolds and access to previously unrealized chemical space. The origins of the unusually low bond orders were investigated using computational methods. These efforts are expected to prompt future studies of molecules that display hyperpyramidalization or atypical bond orders.
