Establishment of Extended Hypervalent Chemistry Containing Acetylene Unit Incorporated in Group 16 Elements Through Synthesis and Property Development

我们发展了扩展的高价化学，它由线性排列的四个或更多原子的线性σ型键组成。在这里，我们的目标是建立新的扩展的高价化学包含乙炔单元纳入16族元素。这种新型扩展的高价化合物由线性分子（或键）轴组成，周围环绕着螺旋分布的原子。测定了它们的结构和性能。这类化合物还制备了由锯齿型键方案组成的化合物，这对于阐明新型延伸高价键的性质很重要。循环系统也在准备中。在化合物中加入较小分子的计划正在进行中。

We have developed the extended hypervalent chemistry, which consists of linearσ-type bonds in linearly aligned four or more atoms. Here, we aimed for the establishment of the novel extended hypervalent chemistry containing acetylene unit incorporated in the group 16 elements. Such novel extended hypervalent compounds were prepared that consist of linear molecular(or bond) axes surrounded by atoms helically distributed around the axes. Their structures and properties were determined. Such compounds were also prepared that consist of zig-zag type bonding schemes, which are important to clarify the nature of the novel extended hypervalent bonds. Cyclic system is also under preparation. Inclusion of smaller molecules in the compounds is planning.
