Trifluoromethylsulfide Anion: Generation and Reaction with Pentafluoropyridine [PDF]

open access: yesCHIMIA, 1985
The anion F3CS⊖, generated from thiocarbonyl difluoride 1 and alkali metal fluorides, reacts with pentafluoropyridine 2 to give high yield of 2,3,5,6-tetrafluoro-4-trifluoromethylthiopyridine 3.

Perfluorination of Aromatic Compounds Reinforce Their van der Waals Interactions with Rare Gases: The Rotational Spectrum of Pentafluoropyridine-Ne [PDF]

open access: yesMolecules, 2021
The rotational spectrum of the pentafluoropyridine-Ne complex, generated in a supersonic jet, has been investigated using chirped-pulse microwave Fourier transform spectroscopy in the 2–8 GHz range.

Reactions of pentafluoropyridine with amidoximes

open access: yesJournal of the Iranian Chemical Society, 2017
In this paper, site reactivity of amidoximes with pentafluoropyridine under basic conditions in dry CH3CN was investigated. The aromatic nucleophilic substitution of pentafluoropyridine with amidoximes occurs in the 4-position of the pyridine ring by the oxygen site of amidoximes and followed by reaction of other sites, depending on reaction conditions.

Reaction of hydroxylated naphtoquinones/antraquinones with pentafluoropyridine. [PDF]

open access: yesSpringerplus, 2016
In this study, the reaction of pentafluoropyridine with hydroxylated naphtoquinones and hydroxylated antraquinones was investigated under basic conditions in DMF. One or two hydroxyl group in naphtoquinones and antraquinones react with pentafluoropyridine to give mono and di-tetrafluoropyridyl naphtoquinones/antraquinones.

One-pot ester and thioester formation mediated by pentafluoropyridine (PFP) [PDF]

open access: yesOrganic & Biomolecular Chemistry, 2022
The use of pentafluoropyridine (PFP) is reported in ester and thioester coupling reactions. The reaction proceeds via an in situ generated acyl fluoride intermediate.

Carboxylic Acid Deoxyfluorination and One-Pot Amide Bond Formation Using Pentafluoropyridine (PFP). [PDF]

open access: yesOrg Lett, 2021
This work describes the application of pentafluoropyridine (PFP), a cheap commercially available reagent, in the deoxyfluorination of carboxylic acids to acyl fluorides. The acyl fluorides can be formed from a range of acids under mild conditions.

Ring Strain-Promoted Activation of Pyridines by a Saturated BSi<sub>2</sub> Cycle. [PDF]

open access: yesAngew Chem Int Ed Engl
We report a highly strained boratadisilirane with the elusive anionic BSi2 ring motif. Cleavage of the Si─Si bond during reactions with pyridine derivatives activates them in three different ways: 1) for pyridine itself selective ortho‐CH activation and concomitant hydrogen transfer to a second pyridine molecule occurs, 2) with dimethylaminopyridine ...

Chiral inheritance effect in the reactive cystine-based coassembly system [PDF]

open access: yesNature Communications
Controlled chemical reactions in the condensed state are key steps in designing smart materials. Due to the absence of diffusion and sufficient molecular collision, the reaction efficiency in the solid or aggregated state is expectedly much lower than ...
