Stabilizing Unusual Main Group Allotropes, Alloys and Radicals Using Carbonyl-Decorated Carbenes

在这个由化学系化学合成计划资助的项目中，德克萨斯州立大学化学和生物化学系的托德·哈德纳尔教授将探索稳定低氧化态和低价主族化合物的方法。除了它们在提高我们对主族化学的理解方面的基本价值外，这些靶向低氧化态主族化合物还可以进一步用于分子水平的能量存储或制备新型纳米结构主族合金。该项目位于有机化学、无机化学和材料化学的交界处，因此非常适合各级科学家的教育。德克萨斯州立大学被归类为西班牙裔服务机构，并处于有利地位，为在科学方面代表性不足的学生提供最高水平的教育和培训。涉及K-12学生的外展活动也将是该资助项目的一部分。具体地说，这项工作将探索一类独特的亲电卡宾在不寻常的配位环境和氧化态中支持主族元素的可能性。通过利用羰基修饰的卡宾作为稳定配体，该项目寻求合成：(A)以重15族元素为中心的稳定的自由基；(B)卡宾负载的端烯和镓；以及(C)形式上零氧化状态的主族同素异形体和合金。

In this project funded by the Chemical Synthesis Program of the Chemistry Division, Professor Todd Hudnall of the Department of Chemistry and Biochemistry at Texas State University will explore the development of methods for stabilizing low-oxidation state and low-valent main group compounds. In addition to their fundamental value in improving our understanding of main group chemistry, these targeted low-oxidation state main group compounds may be further utilized in applications such as energy storage at the molecular level or in the preparation of novel nanostructured main group alloys. The project lies at the interface of organic, inorganic, and materials chemistry, and is therefore well suited to the education of scientists at all levels. Texas State University is classified as a Hispanic Serving Institution, and is well-positioned to provide the highest level of education and training for students underrepresented in science. Outreach activities involving K-12 students will also be part of the funded project. Specifically, this work will explore the potential for a unique class of electrophilic carbenes to support main group elements in unusual coordination environments and oxidation states. By utilizing carbonyl-decorated carbenes as stabilizing ligands, this project seeks to synthesize: (a) stable radicals centered on heavy group 15 elements; (b) carbene-supported terminal borylenes and gallylenes; and (c) formally zero oxidation state main group allotropes and alloys.
