Computational study of the hydrodefluorination of fluoroarenes at [Ru(NHC)(PR₃)₂(CO)(H)₂]: predicted scope and regioselectivities [PDF]

, 2013
Density functional theory calculations have been employed to investigate the scope and selectivity of the hydrodefluorination (HDF) of fluoroarenes, C6F6-nHn (n = 0-5), at catalysts of the type [Ru(NHC)(PR3)(2)(CO)(H)(2)].

Perfluoroheteroaromatics as Tools for Peptide Modification [PDF]

, 2018
The use of peptides as drugs has been hampered due to, in part, poor stability in vivo. To address this issue, heteroaromatics have been investigated in an attempt to improve enzymatic stability.

Synthesis of some fluorinated thiazolopyridine from pentafluoropyridine and 4-phenylsulfonyl tetrafluoropyridine [PDF]

, 2015
In this study, the reaction of pentafluoropyridine and 4-phenylsulfonyl tetrafluoropyridine with difunctional nitrogen and sulfur nucleophiles such as thiourea, thioamide derivatives, and unsymmetrical bidentate nitrogen nucleophiles such as diamino ...

2,3,5,6-Tetrafluoro-[N-(3-aminopropyl)-ε-caprolactam]-4-pyridine

Molbank
The title compound was synthesized at a near-quantitative yield using the nucleophilic aromatic substitution of 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) with perfluoropyridine (PFP). The purity and structure were determined by NMR (1H, 13C, 19F), GC-EIMS,

Transient isomerisation and inverse electronic relaxation of infrared multiple-photon excited Pentafluoropyridine [PDF]

, 1988
Pentafluoropyridine (PFP) undergoes fast structural isomerisation to fulvenes when irradiated with 9R(16) CO2 laser line in the fluence range 0.5-1.5 J/cm2. The unstable fulvenes slowly decay back to PFP in ms time scale.

Amine‐Ligated Boryl Radicals Enables Direct C─F Borylation and Cross‐Couplings of Polyfluoroarenes

Angewandte Chemie, Volume 137, Issue 46, November 10, 2025.
We present a synergistic strategy combining photocatalytic direct C─F borylation of polyfluoroarenes with Suzuki–Miyaura cross‐coupling. The high nucleophilicity of amine‐ligated boryl radicals enables efficient homolytic aromatic substitution of polyfluoroarenes, forming stable amine–borane adducts that resist protodeboronation and can be directly ...

Main Group Metals in Redox Catalysis

European Journal of Inorganic Chemistry, Volume 29, Issue 22, 1 August 2026.
Main group metal redox catalysis is emerging as a credible alternative to transition metal chemistry. Elements from groups 13 to 15 now enable diverse catalytic manifolds, driven by ligand design and control of electronic structure. This review highlights recent advances, key design principles, and remaining challenges, positioning main group metals as

Influence of the Diphosphine Coordinated to Molybdenum and Tungsten Triangular M3S4 Cluster Hydrides in the Catalytic Hydrodefluorination of Pentafluoropyridine [PDF]

, 2015
Hydrido molybdenum and tungsten(IV) cluster cations of formula [M3S4H3(dppe)3]+ (dppe = 1,2-(bis)dimethylphosphinoethane), [Mo-1]+ (M = Mo) and [W-1]+ (M = W), have been isolated by reacting their halide precursors with borohydride.

CF and CH Bond Activation Reactions of Fluorinated Molecules at Rhodium Pincer Complexes

Zeitschrift für anorganische und allgemeine Chemie, Volume 652, Issue 2, 5 February 2026.
Hydrido Rh pincer complexes showed C–F bond activation reactivity with a selectivity at the para position of pentafluoropyridine and octafluorotoluene. The C–H bond activation capability was unleashed by irradiation with UV light to obtain a deprotonated and coordinative unsaturated pincer complex intermediate as the active species.
