Résumé Photoinduced electron transfer is the key step in photoredox catalysis. We will briefly review the essential parameters affecting photoinduced electron transfer and how we can control them for the benefit of synthesis. Next, we discuss recent …

La vidéo sera disponible prochainement. Résumé Ce cours se focalisera sur l'un des cinq facteurs globaux de perte de biodiversité, les invasions biologiques. Au travers d'exemples variés, nous explorerons les définitions, les concepts, les patrons et …

La vidéo sera disponible prochainement. Plan du cours : modèle de Voevodsky des ensembles simpliciaux et caractère non effectif de ces modèles   ; modèles effectifs avec ensembles cubiques   ; application à une définition de structure de modèle la Quillen …

Résumé Since the pioneering report of the oxidative three-component Passerini reaction using a stoichiometric oxidant, [1] oxidative Isocyanide-based multicomponent reactions (IMCRs) have opened new avenues for accessing diverse chemical space from …

Résumé Our group aims to study the total synthesis of complex natural products. We particularly deploy oxidative coupling strategies via single electron transfer (SET) processes among others tactics. We also study electrochemistry to access three …

Résumé Historically, group-1 alkali metal chemistry is dominated by +1 oxidation state. As the least electronegative elements in the Periodic Table, zero-valent alkali metals are prone to give out their only valence shell electron, i.e., acting as strong …

Résumé As part of the organic chemistry, radical chemistry is an important research area as the one electron reactivity is complementary to the ones of the two electrons and polar manifolds. In this regard, electrochemistry, which enjoy a renewal, offers …

Résumé Originally discovered via vapor-phase pyrolysis of p -xylene, 1 [2.2]paracyclophanes (pCps) have garnered significant attention due to their unique three-dimensional architecture 2 and inherent planar chirality. 3 Despite their promising …

Résumé We demonstrate water activation by a photocatalytic phosphine-mediated radical process, generating a PR 3 -H 2 O radical cation intermediate, where both hydrogen atoms are used in the following chemical transformation through sequential cleavage of …

Résumé Over the last three decades, the highly tunable properties of NHCs and other stable singlet carbenes have led to a variety of applications. We will discuss a novel facet of carbenes, i.e., their reductive properties, which allows carbenes to …

Résumé Computational quantum physics has recently seen a dramatic increase in its capabilities, precision, and predictive power. The advances have been driven by method and code development, benchmark, and collaboration. Together with exciting recent …

Résumé Although the genome is often called the blueprint of an organism, it is perhaps more accurate to describe it as a parts list composed of the various genes that may or may not be used in the different cell types of a multicellular organism. Although …

Résumé Après une incursion dans les tragédies qui évoquent des sacrifices humains, ce sont les sacrifices animaux qui sont analysés dans trois tragédies : l' Agamemnon  d'Eschyle, l' Électre d'Euripide et l' Antigone de Sophocle. L' Agamemnon , où était …

Résumé François-Marie Bréon introduira le colloque en rappelant le contexte du changement climatique en cours et du besoin à limiter le réchauffement à moins de 2 degrés.   Il décrira le concept de géo-ingénierie en distinguant les techniques qui visent à …

Résumé This presentation explores geoengineering – a set of ideas aimed at cooling the planet if cutting greenhouse gas emissions isn’t enough to stop climate change. It looks at two main strategies: Solar Radiation Management (SRM) and Carbon Dioxide …
