Rational Design of Ruthenium Complexes: P,Arene-Chelation and Anion Effects in Bond Activation and Catalysis

My PhD research focused on designing better metal catalysts made from ruthenium, a relatively affordable precious yet versatile metal, to make important chemical reactions faster, cleaner, and more reliable. I developed new ways to hold and protect reactive ruthenium atoms so that they stay stable instead of breaking themselves apart, while still being able to activate strong chemical bonds. I also showed that small changes in the “counter-ions” around the metal can greatly improve how well the catalysts work in making one mirror image of a molecule, which is crucial for pharmaceuticals. Overall, this work provides new design rules for building more efficient and selective Ru-based catalysts, helping chemists make  medicines and fine chemicals with less waste, lower energy use, and better control over product quality.
