CAREER: Trimetallic Complexes as Mechanistically Novel Reductants

Seth N.圣母大学化学系的布朗是 由教师早期职业发展（CAREER）奖的支持，从 无机、生物无机和有机金属化学专业。 具有配位不饱和钛中心的三金属配合物， 每一个都能作为一个单电子还原剂， 使用各种具有胺或羟基的靶向配体， 部分，作为模板。 三钛原子簇的能力 小分子中的原子，通过还原形成帽簇 将检查解理。 此外，一个本科实验 实验室课程将被设计并引入课程， 一种教学生建模的工具。 该课程的目标 是培养本科生良好的实验设计技能。 氧或氮的还原是使用这些化合物的关键步骤。 通过生物系统或在工业中使用含钛分子 流程. 拟议的研究将提供更多的见解， 从氨的生物生产到地表 催化反应。 该项目的教育部分将 研究本科化学教育的新方法。

Dr. Seth N. Brown, Department of Chemistry, University of Notre Dame, is supported by a Faculty Early Career Development (CAREER) award from the Inorganic, Bioinorganic and Organometallic Chemistry Program. Trimetallic complexes with coordinatively unsaturated titanium centers, each capable of acing as a one-electron reductant, will be synthesized using a variety of targeted ligands, possessing amine or hydroxyl moieties, as templates. The ability of tri-titanium clusters to abstract atoms from small molecules, forming capped-clusters, via reductive cleavage will be examined. Additionally, an undergraduate experimental laboratory course will be designed and introduced into the curriculum as a vehicle to teach students about model-building. The goal of the course is to develop good experimental design skills in undergraduates. The reduction of oxygen or nitrogen is a key step in the use of these titanium-containing molecules by biological systems or in industrial processes. The proposed studies will provide additional insight into topics ranging from the biological production of ammonia to surface catalyzed reactions. The education component of this project will examine new approaches in undergraduate chemistry education.
