CAREER: Redox-Active Ligand-Mediated Multielectron Bond-Making and Bond-Breaking Reactions at Later First-Row Transition Metal Centers

该奖项是根据2009年美国复苏和再投资法案（公法111-5）资助的。无机、生物无机和有机金属化学项目支持乔治亚理工学院（GIT） Jake Soper教授的研究，以研究更具成本效益的3d金属催化剂的发展，作为昂贵的铂族金属催化剂在小分子活化和功能化方面的替代品。这项研究有望增强在温和条件下使用分子氧作为选择性氧化剂的能力。这个具有挑战性的项目通过将氧化还原活性、带电定位的儿茶酚酸盐和偕胺酚酸盐配体纳入金属配位球，研究了后一排金属离子（通常只影响一个电子氧化还原变化的离子）的多电子氧化还原能力。这些配体提供额外的一个或两个电子转移能力。碳-碳和碳杂原子键组装的新方法也由此产生。该教育计划包括开发一个新的系列讲座，重点是能源相关的研究，将向佐治亚州亚特兰大西湖高中的初级AP学生展示化学基础知识。该系列讲座的机制已被映射到西湖高中的其他化学课程，以及乔治亚州和全国的类似课程中。该校化学与生物化学学院为即将进入大学的高三学生提供了一系列为期五周的暑期实验室实习。该教育计划增加了未被充分代表的群体对化学的参与。

This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5). The Inorganic, Bioinorganic and Organometallic Chemistry Program supports the research of Professor Jake Soper of the Georgia Institute of Technology (GIT) to examine the development of more cost-effective 3d metal catalysts as surrogates for expensive platinum group metal catalysts in small molecule activation and functionalization. The research promises an enhanced ability to use molecular oxygen as a selective oxidant under mild conditions. This challenging project examines the multiple electron redox capacity in later first row metal ions (ions that typically effect only one electron redox changes) by incorporating redox-active, charge-localized catecholate and amidophenolate ligands into the metal coordination sphere. These ligands supply an additional one or two electron transfer capability. New methods for the assembly of carbon-carbon and carbon-heteroatom bonding also result from this research. The educational plan includes the development of a new lecture series, focusing on energy-related research which will demonstrate chemistry fundamentals to junior Advanced Placement (AP) students at Westlake High School in Atlanta, Georgia. Mechanisms have been mapped to transfer this lecture series to other chemistry classes at Westlake High School as well as to similar programs in the state of Georgia and nationwide. A series of five-week summer laboratory internships for college-bound high school juniors and seniors is in place in the School of Chemistry and Biochemistry at GIT. The education program increases the participation of underrepresented groups in chemistry.
