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

无机化学、生物无机化学和金属有机化学项目的这一奖项支持哥伦比亚大学化学系的Gerard F.R.Parkin在合成新型主族化合物方面的研究。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，以稳定正在研究的官能团。这类化合物包括各种三(吡唑基)硼酸盐、双和三(硫代咪唑基)氢硼酸酯配体、手性硼配体以及以一价镓为给体原子的配体。主族元素在合成化学、固态材料和催化反应中具有重要的应用。这个项目的目的是了解元素周期表中一些较重的S-和P-块的一些不寻常的成键和结构性质。了解氮化镓的成键可能有助于深入了解气相合成材料的途径。研究生和博士后将学习严格的综合方法，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.
