Abstract Ever since his discovery in 1856, Neanderthal has been the subject of numerous figurative representations, almost systematically on scientific grounds. The results of these associations between artists and scientists have not escaped numerous …

Abstract Carbon-hydrogen bonds are the most prevalent functionality in organic chemistry constituting the scaffolding of most molecules. Activation of these typically strong bonds has been the subject of intense interest for more than two decades. The use …

Abstract IUPAC defines a “mechanochemical reaction” as a “chemical reaction 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 metals …

Abstract 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 …

Abstract The writing of law, particularly in the 2nd millennium B.C., took different forms depending on the type of source, both in terms of modes of expression and the content of the rules used. This diversity reflects the varied purposes of legal …

Abstract 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 …

Abstract 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 …

Abstract 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 …

Abstract 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 …
