Synthetic, Structural and Mechanistic Studies of Main Group Element Complexes: Atom Transfer Reactions and Subvalent Compounds.

该奖项在无机、生物无机和有机金属化学项目中支持哥伦比亚大学杰拉德·帕金教授的研究，以获取与主要族元素化学有关的基本信息。主族元素的化合物有许多重要的应用，从用作催化剂到用作固态器件。对主族化学的基础研究提供了重要的贡献，提供了对(1)进一步开发这些元素的现有应用和(2)发现新的应用至关重要的知识。本研究计划的主要目的是阐明主族金属在不同配位环境下的结构和反应化学。特别是，建议的研究将集中在主族金属之间的原子转移反应和使用多齿刘易斯酸/刘易斯碱杂化配体。原子转移是一类基本的反应，在主族金属化学中很少被研究，提出的研究将揭示这种本质上有趣的转变。路易斯酸是不常见的配体，但拟议的研究将把这种功能纳入新的多齿配体中，用于合成提供初始亚价金属中心来源的化合物。这项研究将由本科生、研究生和博士后进行，他们将接受广泛的培训，学习通过研究文献和设计和实施精心构思的实验来解决研究问题。此外，课题组亦会为本地中学生提供化学示范。

This award in the Inorganic, Bioinorganic and Organometallic Chemistry program supports research by Professor Gerard Parkin at Columbia University to obtain fundamental information concerned with the chemistry of the main group elements. Compounds of the main group elements have many important applications that range from their use as catalysts to their use as solid-state devices. Fundamental research into main group chemistry provides an important contribution by providing the knowledge that is essential to (i) develop further the existing applications of these elements and (ii) discover new applications. The principal objective of this research program is to elucidate the structures and reaction chemistry of the main group metals in their various coordination environments. In particular, the proposed research will focus on atom transfer reactions between main group metals and the use multidentate Lewis acid/Lewis base hybrid ligands. Atom transfer is an elementary class of reaction that has been little investigated in main group metal chemistry and the proposed studies will shed light on this intrinsically interesting transformation. Lewis acids are uncommon ligands, but the proposed research will incorporate this function into novel multidentate ligands that will be used to synthesize compounds providing sources of incipient subvalent metal centers.The research will be performed by undergraduate, graduate and postdoctoral students who will receive broad training in learning to solve research problems by both studying the literature and by designing and conducting well-conceived experiments. In addition, the research group will also provide chemistry demonstrations for local secondary school students.
