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

该奖项由克莱姆森大学无机、生物无机和有机金属化学项目颁发，以支持格雷戈里·罗宾逊博士的研究。罗宾逊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。研究了有机铝基团与大环胺、多齿开链胺和氮杂环的相互作用。初步结果表明，这些体系在不寻常的三角双锥体、方锥体和八面体配位环境中含有铝中心。铝原子的配位将通过单晶x射线衍射和铝-27核磁共振来确定。这些不寻常化合物的热行为及其作为陶瓷材料单源分子前驱体的可行性将被研究。有机铝化学是有机金属化学中一个重要而又容易被忽视的领域。除了填补我们在铝化学知识方面的严重空白外，该项目还将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前体具有潜在价值。

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.
