Sustainable Catalytic C-H Bond Functionalization (CatCHFun)
Date du début: 1 oct. 2012, Date de fin: 30 sept. 2017 PROJET  TERMINÉ 

The impressive progress in synthetic organic chemistry during the past century has propelled this discipline to its current central place as the key enabling technology in the physical and life sciences. Despite these remarkable advances, our ability to construct molecules of even moderate structural complexity remains unsatisfactory, since these syntheses continue to be inefficient, rely on a high number of reaction steps, and generate undesired, often toxic waste. These features led to the general need for greener transformations that will stimulate the development of more sustainable chemical industries.Conventional approaches in synthetic organic chemistry make use of starting materials displaying specific functional groups, the installation of which results in costly reaction and purification steps. Therefore, an environmentally-sound and economically-attractive alternative is represented by the direct functionalization of ubiquitous carbon-hydrogen (C–H) bonds. These transition-metal-catalyzed processes avoid prefunctionalization strategies, prevent the formation of undesired waste, and thus enable an overall streamlining of organic synthesis.While considerable recent progress has been accomplished in C–H bond functionalizations, available methodologies continue to be limited in scope, and key challenges are still to be overcome. Establishing a full set of sustainable C–H bond functionalization protocols will undeniably have a tremendous impact on various applied areas, such as drug discovery, chemical industries or material sciences.
