The Inorganic, Bioinorganic and Organometallic Chemistry Program supports the research of Andrei N. Vedernikov, Department of Chemistry, University of Maryland - College Park, investigating the selective aerobic functionalization of alkanes, olefins, and arenes using water tolerant platinum complexes. These platinum complexes will employ semi-labile, facially chelating NNO-donor ligands such as di(2-pyridyl)methanesulfonates and di(2-pyridyl)- or di(2-imidazolyl)phosphinates. Computational studies (DFT) will be correlated with the experimental observations to explore the mechanistic aspects of this complicated system. These proposed catalytic reactions, in particular, are expected to fundamentally influence the chemical and petroleum industries, enabling the production of methanol from methane, glycols from olefins and phenol derivatives from arenes, using environmentally-friendly methods. Undergraduate and graduate research students will participate in every aspect of the synthesis, characterization and reactivity studies, gaining important insights into responsible alternatives for the preparation of chemical and petrochemical feedstocks.

无机，生物无机和有机化学计划支持安德烈N。Vedernikov，化学系，马里兰州大学帕克分校，研究了使用耐水铂络合物的烷烃、烯烃和芳烃的选择性有氧官能化。这些铂络合物将采用半不稳定的、表面螯合的NNO-供体配体，例如二（2-吡啶基）甲磺酸酯和二（2-吡啶基）-或二（2-咪唑基）次膦酸酯。 计算研究（DFT）将与实验观察相关联，以探索这个复杂系统的机制方面。特别地，这些提出的催化反应预计将从根本上影响化学和石油工业，使得能够使用环境友好的方法从甲烷生产甲醇、从烯烃生产二醇和从芳烃生产苯酚衍生物。本科生和研究生研究生将参与合成，表征和反应性研究的各个方面，获得重要的见解，为化学和石化原料的制备负责任的替代品。
