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

这个奖项在无机，生物无机和有机化学计划支持研究杰拉德F。R.哥伦比亚大学化学系的Parkin教授，关于新型主族化合物的合成。制备的s-和p-嵌段化合物将具有目前未知的功能，例如末端氮化镓单元。 这些配合物的合成将依赖于所构建的配体的使用，以便稳定所研究的官能团。这些主族元素包括各种三-（吡唑基）硼酸盐和双-和三-（巯基咪唑基）硼氢化物配体、手性硼配体以及以单价镓为给体原子的配体。该项目旨在了解周期表中s和p区的一些较重成员的一些不寻常的键合和结构特性。了解氮化镓键合可以提供一些洞察材料的气相路线。 研究生和博士后学生将学习严格的合成方法，并参加小组项目。

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.
