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 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 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 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 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 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 …

Christopher Domínguez Michael est invité par l'assemblée du Collège de France sur proposition du Pr William Marx. La conférence est en espagnol avec traduction en surtitrage. Résumé L'exercice de la critique littéraire depuis l'Amérique latine, …

Résumé Nous parlons volontiers de « protéger la nature », de « préserver la biodiversité », de « services écosystémiques ». Mais derrière ces formules se cache une vision du monde bien particulière : celle d'un humain séparé du vivant, qui décide …

Résumé In the first lecture the issue of changing biblical interpretation in the South African context since the 1990s when Nelson Mandela was released and the ANC party unbanned, and since 1994 when the first democratic post-apartheid elections were …
