Leonardo da Vinci's quote that "simplicity is the ultimate sophistication" is possibly the most appropriate description of organometallic catalysis. Whereas organic chemistry is exemplified by hundreds of different reactions (many egotistically named after those who discovered them) transition metal inorganic and organometallic compounds only undergo eight metal centered reactions, of which, four are the reverse (equilibrium) reactions of four others, thus limiting further the possible reactions, that need to be considered in transition metal inorganic and organometallic chemistry, to just four: ligand association/ligand dissociation, ligand insertion/ligand elimination, oxidative addition/reductive elimination, and electron transfer (redox). This makes understanding and prediction of catalytic cycles simple, since any overall reaction must be a combination of these reactions. For added simplicity, electron transfer is a reaction more associated with metal containing biological catalyst pathways rather than organometallic catalysis. Given the limited potential reactions available to organometallic transition metal compounds it should be possible to develop a simple approach to the prediction and rationalization of any catalytic reaction in which they act as the catalysts or catalyst precursor (pro-catalyst).
Über die Autorin bzw. den Autor
After having gained his BSc and PhD degrees from Imperial College (London) and performing post-doctoral research at the University of Texas at Austin, Barron spent eight years as a Professor of Chemistry at Harvard University before moving to Rice University in 1995 where he is the Welch Chair of Chemistry and Professor of Nanoengineering and Materials Science. In 2014 he was appointed the Sêr Cymru Chair of Low Carbon Energy and Environment at Swansea University, and founded the Energy Safety Research Institute, where he is the Director. He is a visiting professor at both the University of Arizona and Universiti Technology Brunei. He is the author of over 550 publications, 40 Patents, 15 books, and has graduated 30 PhD students. His early research focused on the chemistry of aluminum and related elements and spanned catalysis, electronic materials and nanotechnology. His current research involves the application of chemistry, nanotechnology and materials science to fundamental problems in energy, the environment and industrial decarbonization. Prof. Barron is a Fellow of the Royal Society of Chemistry, and the recipient of several awards, including: Star of Asia International Award, the Hümboldt Senior Scientist Research Award, the Corday Morgan Medal, the Meldola Medal, and the first Welch Foundation Norman Hackerman Award. In 2009 Barron was appointed as the Prince of Wales Visiting Innovator. In 2011 he won both the Lifetime Achievement Award in Nanotechnology and the World Technology Award (in Materials). Barron is the co-founder of several companies over a diverse range of industries. His latest commercialization ventures are technologies for water purification of produced water and an anti-viral mask for the COVID crisis. In addition to teaching in chemistry and materials science, Prof. Barron created the first educational programs at Rice University to span the schools of Science, Engineering and Management. For relaxation Barron races cars, as both an amateur and professional, on both sides of the Atlantic.
