Research in the Hayes group focuses on the preparation and study of high-energy and reactive molecules for application in new chemical transformations and catalysis. Specifically, we are interested in the development of catalytic systems for directly converting inexpensive and abundant hydrocarbons into useful organic compounds. Such derivitization is especially desirable for smaller hydrocarbons, such as methane, which are produced as undesirable side products in the petrochemical industry and contribute significantly to greenhouse gases. We use molecules known as phosphido ligands to stabilize high oxidation state late transition metal complexes with unusual geometries and unique electronic properties to promote the activation of chemically inert small molecules. The isolation of this class of compound should also provide insight into fundamental questions regarding bonding and structure and contribute to the knowledge base used by chemists to design new catalytic reactions. This additional knowledge will ultimately allow for rational improvements to current catalytic systems and the development of entirely novel reactions.

海耶斯小组的研究重点是制备和研究高能量和反应性分子，以应用于新的化学转化和催化。具体来说，我们感兴趣的是开发催化系统，将廉价和丰富的烃直接转化为有用的有机化合物。这种衍生化对于较小的烃如甲烷是特别期望的，所述较小的烃在石化工业中作为不期望的副产物产生并且显著地贡献温室气体。我们使用被称为磷配体的分子来稳定具有不寻常几何形状和独特电子性质的高氧化态后过渡金属络合物，以促进化学惰性小分子的活化。这类化合物的分离还应该提供有关键合和结构的基本问题的见解，并有助于化学家设计新的催化反应所使用的知识库。 这些额外的知识最终将允许对现有催化系统进行合理的改进，并开发全新的反应。
