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.

在由化学综合和催化计划资助的职业奖中，圣路易斯华盛顿大学化学系的Liviu Mirica教授将合成新颖的Promagnetic PD（III）和NI（III）复合物，并详细研究其电子性能和反应性，并具有涉及这些常见氧化氧化的催化转化的长期目标，这些催化转化的长期目标涉及这些常见的氧化。特别令人感兴趣的是PD介导的有氧氧化C-H功能化反应以及与交叉偶联反应有关的有机金属Ni（III）复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的结合，因此将为学生提供跨学科培训以及发展广泛的科学技能的机会。此外，这些研究将与外展活动完全融合，这些活动将通过来自圣路易斯都会区公立学校的讲座和演示来暴露学生的学生，从而使学生成为了广泛的化学反应的催化剂。拟议的研究应导致与有机合成相关的独特金属介导的氧化转化，这可能会影响化学家将原子放在一起以更有效和经济地构建复杂分子的方式。
