Research in the Hayes group involves the synthesis of high-energy and reactive inorganic molecules for application in new chemical transformations and catalysis. Three unique projects directly address this goal. The first involves the preparation of novel tridentate pincer ligands to support low-valent complexes and metal main-group multiple bonding within lanthanide and group 3 metals. Another project tackles the challenge of preparing new materials that are both biodegradable and biocompatible through the use of discrete alkaline earth metal complexes. The third project is tailored toward the catalytic functionalization of hydrocarbons and small molecule activation. Students within the Hayes group will learn inert atmosphere methodologies (high-vacuum, Schlenk and glove-box) and characterize new compounds using a wide array of spectroscopic techniques (multinuclear NMR, IR, UV-Vis, ESR), Mass Spectrometry, X-ray crystallography and analytical methods.
