Synthetic, Structural, and Mechanistic Studies of s- and p-Block Element Complexes with Reactive Functionalities

这个无机、生物无机和有机金属化学项目的奖项支持哥伦比亚大学化学系的Gerard F. R. Parkin在合成新型主基团化合物方面的研究。所制备的s-和p-嵌段化合物将具有目前未知的功能，例如终端氮化镓单元。这些配合物的合成将依赖于为稳定所研究的功能而构建的配体的使用。这些配体包括各种三（吡唑基）硼酸盐、二和三（巯基咪唑基）氢硼酸盐配体、手性硼配体以及以单价镓为供体原子的配体。主族元素在合成化学、固体材料和催化反应中有各种重要的应用。该项目旨在了解元素周期表中s-和p-基团中一些较重成员的一些不寻常的键和结构特性。了解氮化镓键合可以为材料的气相路径提供一些见解。研究生和博士后将学习严格的合成方法，并参与小组项目。

This award in the Inorganic, Bioinorganic, and Organometallic Chemistry Program supports research by Gerard F. R. Parkin of the Department of Chemistry, Columbia University, on synthesis of novel main group compounds. The s- and p-block compounds prepared will feature currently unknown functionalities, such as a terminal gallium nitride unit. The syntheses of these complexes will rely upon the use of ligands constructed so as to stabilize the functionalities under investigation. These include various tris-(pyrazolyl)borate and bis- and tris-(mercaptoimidazolyl)hydroborate ligands, chiral-at-boron ligands, and ligands featuring monovalent gallium as the donor atom.The main group elements have a variety of important applications in synthetic chemistry, solid state materials, and catalytic reactions. This project aims at understanding some of the unusual bonding and structural properties of some of the heavier members of the s- and p-block of the periodic table. Understanding gallium-nitride bonding may provide some insight into gas phase routes to materials. Graduate and postdoctoral students will learn rigorous synthetic methodologies and participate in group projects.
