Organoaluminum Coordination Chemistry: New Concepts in Synthesis, Structure, and Reactivity

该奖项授予克莱姆森大学无机化学、生物无机化学和金属有机化学项目，以支持格雷戈里·罗宾逊博士的研究。Robinson博士的研究涉及有机铝：胺配合物的设计、合成、结构和反应性，并提供了主要族元素配位所需的结构数据。有机铝部分与大环胺、多齿开链胺和氮杂环的相互作用将被研究。初步结果表明，这些体系在不寻常的三角双金字塔、方形金字塔和八面体配位环境中含有铝中心。铝原子(S)的配位将通过单晶X射线衍射和铝-27核磁共振确定。这些特殊化合物的热行为以及它们作为单一来源的陶瓷材料分子前驱体的可行性将被研究。有机铝化学是金属有机化学中一个重要而又被忽视的领域。除了填补我们铝化学知识的严重空白外，该项目还将导致合成新的有机铝化合物，这些化合物将作为制备氮化铝等陶瓷材料的潜在价值。

This award is made in the Inorganic, Bioinorganic and Organometallic Chemistry Program to Clemson University to support the research of Dr. Gregory Robinson. Dr. Robinson's research deals with the design, synthesis, structure and reactivity of organoaluminum:amine complexes and provides needed structural data on coordination of main group elements. The interactions of organoaluminum moieties with macrocyclic amines, multidentate open-chain amines and nitrogen heterocycles will be investigated. Preliminary results indicate that these systems contain aluminum centers in unusual trigonal bipyramidal, square pyramidal and octahedral coordination environments. The coordination of the aluminum atom(s) will be determined by single-crystal X-ray diffraction and aluminum-27 NMR. The thermal behavior of these unusual compounds and their feasibility to function as single-source molecular precursors for ceramic materials will be investigated. %%% Organoaluminum chemistry is an important but rather neglected area of organometallic chemistry. In addition to filling in serious gaps in our knowledge of aluminum chemistry, the project will result in the synthesis of new organoaluminum compounds which will be of potential value as precursors for the preparation of ceramic materials such as aluminum nitride.
