Abstract

Cyclopentadienyl anions ([Cp]^-) are pervasive ligands in coordination chemistry. In contrast, heavy-element derivatives of these ligands, particularly those that feature arsenic, are not as well developed. In this work, a new arsenic-based heterocycle with a structure analogous to [Cp]^- is presented. Reaction of K₃As₇ with benzyl azide (BnN₃) leads to fragmentation of the [As₇]^3- core and C-H activation of two [BnN] units to give the five-membered arsenic heterocycle [As(NC(Ph))₂]^-. This arsenic heterocycle was studied by nuclear magnetic resonance and UV-vis spectroscopy, X-ray diffraction, and its electronic structure was investigated computationally.

1,2,4-重氮杂脲阴离子的合成与表征。

环戊二烯阴离子（[Cp]-）是配位化学中普遍存在的配体。相比之下，这些配体的重元素衍生物，特别是那些以砷为特征的配体，并没有得到很好的发展。本文提出了一种结构类似于[Cp]-的砷基杂环化合物。K3As7与叠氮苄基（BnN3）反应，导致[As7]3-核断裂，两个[BnN]单元C-H活化，得到五元砷杂环[As(NC(Ph))2]-。采用核磁共振、紫外-可见光谱、x射线衍射等方法对该砷杂环进行了研究，并对其电子结构进行了计算研究。

期刊介绍： Organometallics is the flagship journal of organometallic chemistry and records progress in one of the most active fields of science, bridging organic and inorganic chemistry. The journal publishes Articles, Communications, Reviews, and Tutorials (instructional overviews) that depict research on the synthesis, structure, bonding, chemical reactivity, and reaction mechanisms for a variety of applications, including catalyst design and catalytic processes; main-group, transition-metal, and lanthanide and actinide metal chemistry; synthetic aspects of polymer science and materials science; and bioorganometallic chemistry.
