This award in the Inorganic, Bioinorganic and Organometallic Chemistry program supports research on the stoichiometric and catalytic transformations involving f-element and related organometallic molecules by Professor Tobin Marks of the Chemistry Department at Northwestern University. Using primarily heavier group 14-16 metallocene complexes synthesized by the P.I. and collaborators, reaction calorimetry is utilized to quantify the strengths of metal-ligand multiple bonds. The scope and mechanisms of organolanthanide/actinide catalyzed reactions will be determined, to include hydroamination, phosphination and boration as well as olefin polymerization to produce polymers end-capped with a hetroatom (Si, Sn, B, Al) group.The goal of this research is to discover, understand, improve and apply chemical transformations involving organometallic molecules and molecular fragments to numerous areas of US industrial chemistry. The work focuses on the use of organometallic complexes of lanthanides and actinides, a relatively unexplored area, to effect these transformations which include catalytic processes for the production of fuels, polymeric materials, pharmecuticals and other economically important chemicals. This project will help to build both a broad knowledge base and a technically skilled cadre of researchers trained to develop more efficient, selective, environmentally benign and economically competitive process technologies.

这个无机、生物无机和有机金属化学项目的奖项支持西北大学化学系Tobin Marks教授对涉及f元素和相关有机金属分子的化学计量学和催化转化的研究。利用主要由P.I.和合作者合成的较重的14-16基团的金属配合物，反应量热法被用来量化金属配体多键的强度。将确定有机镧系/锕系催化反应的范围和机理，包括氢胺化、磷化和硼化以及烯烃聚合，以产生端部有异原子（Si、Sn、B、Al）基团的聚合物。这项研究的目标是发现、理解、改进和应用涉及有机金属分子和分子片段的化学转化到美国工业化学的许多领域。这项工作的重点是利用镧系元素和锕系元素的有机金属配合物，这是一个相对未开发的领域，以实现这些转变，包括生产燃料、聚合材料、药品和其他经济上重要的化学品的催化过程。这个项目将有助于建立一个广泛的知识基础和一支受过训练的技术熟练的研究人员队伍，以发展更有效、有选择性、无害环境和在经济上具有竞争力的工艺技术。
