In this CAREER award funded by the Chemical Synthesis and Catalysis Programs, Professor Liviu Mirica of the Department of Chemistry at Washington University in St. Louis will synthesize novel paramagnetic Pd(III) and Ni(III) complexes and investigate in detail their electronic properties and reactivity, with the long-term goal of developing catalytic transformations that involve these less common oxidation states. Of particular interest are Pd-mediated aerobic oxidative C-H functionalization reactions and detailed reactivity studies of organometallic Ni(III) complexes relevant to cross coupling reactions. These studies include a combination of synthetic organometallic and inorganic chemistry, catalysis, electrochemistry, and physical inorganic spectroscopy, and thus will provide the students interdisciplinary training and the opportunity to develop a broad range of scientific skills. In addition, these studies will be fully integrated with outreach activities that will expose students from underrepresented groups to chemistry through lectures and demonstrations at public schools from the St. Louis metro area.Palladium and nickel complexes act as catalysts for a wide range of chemical reactions that are essential for the synthesis of commodity chemicals, fine chemicals, and bioactive compounds. The proposed research should lead to unique metal-mediated oxidative transformations relevant to organic synthesis that may impact how chemists put atoms together to build complex molecules more efficiently and economically.

在这个由化学合成和催化项目资助的职业奖中，圣路易斯华盛顿大学化学系的 Liviu Mirica 教授将合成新型顺磁性 Pd(III) 和 Ni(III) 配合物，并详细研究它们的电子特性和反应性，长期目标是开发涉及这些不常见氧化态的催化转化。特别令人感兴趣的是 Pd 介导的有氧氧化 C-H 官能化反应以及与交叉偶联反应相关的有机金属 Ni(III) 配合物的详细反应性研究。这些研究包括合成有机金属和无机化学、催化、电化学和物理无机光谱学的结合，因此将为学生提供跨学科培训和发展广泛的科学技能的机会。此外，这些研究将与推广活动充分结合，通过在圣路易斯都市区公立学校的讲座和演示，让弱势群体的学生接触化学。钯和镍络合物可作为各种化学反应的催化剂，这些化学反应对于合成商品化学品、精细化学品和生物活性化合物至关重要。拟议的研究应该会产生与有机合成相关的独特的金属介导的氧化转化，这可能会影响化学家如何更有效、更经济地将原子组合在一起以构建复杂分子。
