Résumé La bonne santé du vivant, humain comme non humain, est avant tout la synthèse des conditions environnementales auxquelles celui-ci est exposé. Or, maintes menaces sanitaires se profilent à l'horizon : transmission accélérée de maladies infectieuses …

Résumé Electrochemical reduction of carbon dioxide can yield valuable chemicals, energy carriers, and renewable fuels that serve as storage forms of renewable energy. This transformation can be achieved using molecular catalysts immobilized on conductive …

Résumé Activation of carbene precursors by planar, low-spin cobalt(II) complexes leads to formation of ‘carbene radical’ intermediates. 1 These are intrinsically reactive metal-bound carbon radicals (Figure 1), useful for catalytic synthesis of a variety …

Résumé Polyoxometalates (POMs) form a versatile family of molecular oxide clusters of the early transition metals endowed with exceptional redox properties, which have driven applications in photo/electro-catalysis, photo/electro-chromic materials, energy …

Résumé Activation of small molecules by donor-acceptor systems is conceptually important as many catalytic processes rely on the synergistic action of electron-rich and -poor sites to cooperatively activate and cleave bonds. This pertains to both the …

Résumé Over the past 20 years, significant research has been directed toward the development of new methodologies for synthetic efficiency and atom economy processes in the presence of gold complexes. 1 We have been initially engaged in a wide project …

Résumé Part I  – Our approach to cross-coupling uses sulfoxides to activate substrates as sulfonium salts. In particular, sulfonium salts, generated from arenes, 1  and new sulfonium salts generated from alternative feedstocks, 2 can be exploited in …

Résumé Visible-light photoredox catalysis provides powerful opportunities for redox transformations under mild conditions;1 however, the development of efficient, low-cost, and metal-free photocatalysts remains a central challenge.1b In this talk, I will …

Résumé Electron transfer-mediated functionalizations present new avenues for the construction of carbon–carbon and carbon–heteroatom bonds from readily available and abundant feedstocks. We have been developing new photocatalytic systems as versatile …

Résumé IUPAC defines a "mechano-chemical reaction" as a "chemical reaction that is induced by the direct absorption of mechanical energy". 1 We investigated a wide range of organic reactions and found that ball milling can affect the oxidation states of …

Résumé In this lecture we extend the construction of the Hyodo-Kato stack to the analytic prismatization. We will focus on the study of the Hodge-Tate stack and its relation with geometric Sen …
