Autor: Siby Mathew, Yuki Naganawa, Fan Jiang, Raphael Wischert, Stephane Streiff, Pascal Metivier, Yumiko Nakajima

Publikováno v: Macromolecular Rapid Communications. 44

Placement of phosphorus in the polymer main chain leads to organophosphorus polymers with potentially unique chemical and physical properties. Here, we demonstrate that the Abramov phosphonylation reaction can be extended to the synthesis of such pol

Publikováno v: European Journal of Organic Chemistry. 2020:3219-3224

Herein we report a comparison of Lewis acidity indicators (affinity scales, electronegativity, Fukui functions, global electrophilicity index) with a new in silico Beckett–Childs descriptor based on the build‐up of partial charge, computed by DFT

Selective Acid-Catalyzed Hydroarylation of Nonactivated Alkenes with Aniline Assisted by Hexafluoroisopropanol

Autor: Karine De Oliveira Vigier, Anaelle Humblot, Fan Jiang, François Jérôme, Marc Pera-Titus, Raphael Wischert, Gongming Peng

Publikováno v: The Journal of organic chemistry. 86(24)

The catalytic hydroarylation of nonactivated alkenes with aniline is a reaction of high interest, aiming at providing C-functionalized aniline derivatives that are important precursors for the fabrication of polyurethanes. However, this reaction rema

International audience; Isosorbide isomerisation is a known reaction that can proceed over Ru and Ni-based heterogeneous catalysts. As a rule, an exogenous H2 pressure (40–100 bar) is required, even though H2 does not participate stoichiometrically
