This International Collaboration in Chemistry award in the Division of Chemistry supports Professor David A. Vicic at the University of Hawaii to collaborate with Professor Yulia H. Budnikova of the Kazan Scientific Center at the Russian Academy of Sciences in performing electroanalysis on a series of palladium complexes in order to identify new Pd(III) complexes, and to systematically investigate their redox properties under aerobic conditions. These results will be applied to the discovery of new synthetic transformations using the higher oxidation states of palladium and will be extended to electrocatalytic C-H functionalization methods involving nickel. The research aims toward an understanding of the details of transformations that could enable new reactions with nickel, which would complement the existing chemistry of palladium.Complementing the existing synthetic chemistry of palladium with corresponding reactions using nickel could lower the costs of catalysis and enable greener synthetic methods. The tabulation of redox potentials for a series of palladium complexes will help guide chemists in choosing an appropriate oxidant for high-valent transformations. New electrochemistry experiments derived from this research will be incorporated into laboratory courses in Advanced Inorganic Chemistry and Spectroelectrochemistry.

化学系的这一国际合作奖支持夏威夷大学的David A.Vicic教授与俄罗斯科学院喀山科学中心的Yulia H.Budnikova教授合作，对一系列钯(III)配合物进行电分析，以确定新的Pd(III)配合物，并系统地研究它们在有氧条件下的氧化还原性能。这些结果将应用于利用钯的较高氧化态发现新的合成转化，并将扩展到涉及镍的电催化C-H功能化方法。这项研究旨在了解可以与镍发生新反应的转化细节，这将补充现有的钯化学。用镍进行相应的反应来补充现有的钯合成化学可以降低催化成本，并实现更绿色的合成方法。一系列钯配合物的氧化还原电势的列表将有助于指导化学家为高价转化选择合适的氧化剂。这项研究产生的新的电化学实验将被纳入高级无机化学和光谱电化学的实验室课程。
