Direct synthesis of acyl fluorides from carboxylic acids using benzothiazolium reagents
Autor: Lilian M. Maas, Alex Haswell, Rory Hughes, Matthew N. Hopkinson
Publikováno v: Beilstein Journal of Organic Chemistry, Vol 20, Iss 1, Pp 921-930 (2024)
2-(Trifluoromethylthio)benzothiazolium triflate (BT-SCF3) was used as deoxyfluorinating reagent for the synthesis of versatile acyl fluorides directly from the corresponding carboxylic acids. These acyl fluorides were reacted with amines in a one-pot

Benzothiazolium salts as reagents for the deoxygenative perfluoroalkylthiolation of alcohols
Autor: Armin Ariamajd, Nils J. Gerwien, Benjamin Schwabe, Stefan Dix, Matthew N. Hopkinson
Publikováno v: Beilstein Journal of Organic Chemistry, Vol 17, Iss 1, Pp 83-88 (2021)
A series of 2-(perfluoroalkylthio)benzothiazolium (BT-SRF) salts have been synthesized that serve as convenient sources of hitherto underexplored perfluoroalkylthiolate anions. An investigation of their reactivity in a deoxygenative nucleophilic subs

A (TD-)DFT study on photo-NHC catalysis: photoenolization/Diels–Alder reaction of acid fluorides catalyzed by N-heterocyclic carbenes
Autor: Andreas Mavroskoufis, Manish Lohani, Manuela Weber, Matthew N. Hopkinson, Jan P. Götze
A comprehensive mechanistic study on the N-heterocyclic carbene (NHC) catalyzed photoenolization/Diels–Alder (PEDA) reaction of acid fluorides was performed in the framework of (time-dependent) density functional theory ((TD)-DFT). The 1,5-hydrogen

Recent advances in the chemistry and applications of N-heterocyclic carbenes
Autor: Maximilian Koy, Frank Glorius, Peter Bellotti, Matthew N. Hopkinson
Publikováno v: Nature Reviews Chemistry. 5:711-725
N-Heterocyclic carbenes, despite being isolated and characterized three decades ago, still capture scientists’ interest as versatile, modular and strongly coordinating moieties. In the last decade, driven by the increasingly refined fundamental und

Radical C−H Trifluoromethoxylation of (Hetero)arenes with Bis(trifluoromethyl)peroxide
Autor: Jonas R. Schmid, Matthew N. Hopkinson, Paul Golz, Sebastian Riedel, Stefan Dix
Publikováno v: Chemistry (Weinheim an Der Bergstrasse, Germany)
Trifluoromethoxylated (hetero)arenes are of great interest for several disciplines, especially in agro‐ and medicinal chemistry. Radical C−H trifluoromethoxylation of (hetero)arenes represents an attractive approach to prepare such compounds, but
