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.

A protocol for the gram-scale synthesis of polyfluoroaryl sulfides via an SNAr step [PDF]

open access: yesSTAR Protocols, 2023
Summary: Polyfluoroaryl sulfide is one of the prevalent motifs ubiquitous in materials and pharmaceutical chemistry. We herein describe a simple yet efficient procedure for their synthesis from readily available thiols and polyfluoroarenes via an SNAr ...

Speciation-Controlled C-F Bond Functionalization Enabled by Zwitterionic Pnictinidenes. [PDF]

open access: yesAngew Chem Int Ed Engl
Zwitterionic pnictinidenes turn C–F activation into C–X bond construction, enabling broad defluorinative functionalization of polyfluoro(hetero)arenes under mild conditions. Rather than following a metallomimetic Sb(I)/Sb(III) redox turnover, catalysis is redirected by ligand scrambling into a redox‐neutral manifold, revealing catalyst speciation as a ...

Molecular engineering of bistetrafluoropyridine aryl ethers: a general platform for stable and programmable amorphous organic solids [PDF]

open access: yesRSC Advances
We report a highly efficient strategy for the synthesis of a novel class of amorphous, small-molecule organic glass formers (MOGs) derived from pentafluoropyridine (PFP). Utilizing a single-step, atom-economical, and highly scalable nucleophilic aromatic

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 ...

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.

Visible-light-promoted direct desulfurization of glycosyl thiols to access C-glycosides [PDF]

open access: yesNature Communications
C-Glycosides are essential for the study of biological processes and the development of carbohydrate-based drugs. Despite the tremendous hurdles, glycochemists have often fantasized about the efficient, highly stereoselective synthesis of C-glycosides ...

Zwitterionic Heavier Pnictinidenes in Redox Catalysis. [PDF]

open access: yesAngew Chem Int Ed Engl
Zwitterionic pnictinidenes: A new class of zwitterionic heavier pnictogen species stabilized by bis(N‐heterocyclic carbene)borate ligands is reported, enabling the isolation of Sb and Bi in multiple oxidation states. These thoroughly characterized systems exhibit cationic character and engage in redox catalysis, facilitating catalytic ...
