This volume presents the latest developments in the use of organometallic catalysis for the formation of bulk chemicals and the production of energy, via green processes including efficient utilization of waste feedstocks from industry. The chemistry of carbon dioxide relating to its hydrogenation into methanol an eco-friendly energy storage strategy and its uses as C1 synthon for the formation of important building-blocks for fine chemicals industry are covered. Catalytic hydrogenations of various functional groups and hydrogen transfer reactions including the use of first row metal catalysts are presented as well as the conversion of alcohols to carboxylates via hydrogen transfer with a zero-waste strategy using water. Transformation of renewable or bio-based raw materials is surveyed through alkene metathesis and C O bond activations and functionalizations. A green aspect for selective formation of C-C, C-O and C-N bonds involves direct regioselective C H bond activations and functionalizations. These transformations can now be promoted under mild reaction conditions due to the use photoredox catalyts. C H bond oxidation using visible light leads mainly to the formation of C O and C N bonds, whereas cross-coupled C C bonds can be formed through the radical additions on (hetero) arenes using photoredox assisted mechanism.
Biografie (Pierre H. Dixneuf)
Pierre H. Dixneuf is professor of chemistry at the University of Rennes, now Emeritus Professor. He has created a team on Organometallic Chemistry and Catalysis, and in 2000 he founded the Research Institute of Chemistry of Rennes. He has developed successively several processes in ruthenium catalysed reactions: transformations of alkynes, incorporation of CO2, ruthenium-vinylidenes and allenylidenes in catalysis, catalytic synthesis of heterocycles, alkene metahesis catalysts and applications, C-H bond activation including in water. He has designed many new ruthenium catalysts especially involving metal-carbene bond. He has published more than 380 papers, edited 2 books and owns 5 patents. He is a member of Institute Universitaire de France (IUF) since 2000.
