Photo-Induced Halogen-Atom Transfer: Generation of Halide Radicals for Selective Hydrohalogenation Reactions
Autor: Lilian Geniller, Marc Taillefer, Florian Jaroschik, Alexis Prieto
Publikováno v: Chemistry (Weinheim an der Bergstrasse, Germany). 28(43)
The first photo-mediated process enabling the generation of halide radicals by Halogen-Atom Transfer (XAT) is described. Contrary to radical transformations involving XAT reactivity, which exploit stable carbon radicals, this unique approach uses 1,2

Radical-Based C−C Bond-Forming Processes Enabled by the Photoexcitation of 4-Alkyl-1,4-dihydropyridines
Autor: Paolo Melchiorre, Sudipta Raha Roy, Luca Buzzetti, Alexis Prieto
Publikováno v: Angewandte Chemie (International Ed. in English)
Angewandte Chemie International Edition
We report herein that 4‐alkyl‐1,4‐dihydropyridines (alkyl‐DHPs) can directly reach an electronically excited state upon light absorption and trigger the generation of C(sp3)‐centered radicals without the need for an external photocatalyst.

Copper-Catalyzed Trifluoromethylation of Hydrazones Leading to the Formation of Quaternary α-Trifluoromethyl Diazenes
Autor: Didier Bouyssi, Nuno Monteiro, Alexis Prieto
Publikováno v: Asian Journal of Organic Chemistry. 5:742-745
The copper-catalyzed azomethine trifluoromethylation of ketone-derived hydrazones with Togni′s hypervalent iodine(III)-CF3 reagent is described. The reaction gives rise to quaternary α-trifluoromethyl diazenes under mild conditions and is proposed
