  • Guillaume Lefèvre
    Chargé de Recherches CNRS (CRCN, Section 12)


    I obtained my PhD in 2012 at the Ecole Normale Supérieure de Paris under the guidance of Dir. Dr. Anny Jutand, where I developed an expertise in molecular electrochemistry used as an investigation tool for mechanistic studies of transition-metal-calatyzed transformations. During this time, I worked in a close collaboration with the group of Pr. Carlo Adamo and Dr. Ilaria Ciofini (ENSCP ChimieParisTech, Paris), where I acquired skills in computational chemistry (DFT techniques applied to organometallic species). During a postdoctoral fellowship in the group of Prof. Peter Legzdins (University of British Columbia, Vancouver, Canada, 2012-2014; DOW Chemicals Fellowship), I worked in the field of C─H activation of saturated hydrocarbons involving tungsten nitrosyl complexes. I joined the CEA as a Chargé de Recherches (CNRS) in September 2014. My research activity in the LCMCE is carried out in collaboration with Dr. Thibault Cantat and focused on the development and mechanistic understanding of new methodologies for the valorization of CO2 and its derivatives. The second part of my activities is centered on mechanistic investigations of low-valent iron-catalyzed transformations in organic synthesis.
