A direct and useful route to difluoroacylsilanes and difluoroacylstannanes and their potential for the generation of structurally diverse difluoroketones

, 2001
Allyl trifluoroethyl ethers 2a–2d were prepared; each underwent efficient dehydrofluorination/metallation and trapping to afford a range of difluoroenol silanes and stannanes which rearranged easily and efficiently to the acyl metals.

Impact of PVDF Homo and Copolymer on Thiophosphate Solid Electrolyte Characteristics and Comprehensive Bulk‐To‐Surface Characterization

Advanced Materials Interfaces, Volume 13, Issue 12, 23 June 2026.
This study examines how a PVDF‐like binder affects the argyrodite Li6PS5Cl electrolyte properties. Using an approach that combines bulk and surface characterization with electrochemistry, we found a chemical interaction between Li6PS5Cl and PVDF, resulting in partial chlorine substitution by fluorine and slightly reduced ionic conductivity.

Carbon-Interacted AlF₃ Clusters as Robust Catalyst for Dehydrofluorination Reaction with Enhanced Undercoordination and Stability

Conversion of potent greenhouse gases, hydrofluorocarbons (HFCs), to value-added hydrofluoroolefins (HFOs) is of great importance. AlF3 catalysts play a major role in this process.

One-Pot Synthesis of 3,5-Disubstituted and Polysubstituted Phenols from Acyclic Precursors

, 2016
A new strategy for the synthesis of 3,5-disubstituted phenols is established through one-pot Robinson annulation of α,β-unsaturated ketones with α-fluoro-β-ketoesters followed by in situ dehydrofluorination and tautomerization.

HFC-134a as a fluorinated building block : short syntheses of α-fluoroenones

, 2000
1,1,1,2-Tetrafluoroethane (HFC-134a) has been transformed into a range of -fluoroenones via a direct route. Dehydrofluorination/metallation allowed trifluorovinylsilanes to be prepared; these could be converted in situ, or isolated and treated further ...

Combustion Synthesis of Amorphous Al and Cr Composite as the Catalyst for Dehydrofluorination of 1,1-Difluoroethane

, 2018
Interaction or lattice doping between Cr and Al contributes to the acidity and catalytic activity of Cr/Al catalysts, which is difficult to be achieved by the conventional preparation methods while maintaining nanostructures.

Enhancing the Alpha-To-Gamma Phase Transition of Poly(vinylidene fluoride) via Dehydrofluorination Modification

Due to the high activating energy, it is very difficult to initiate the α-to-γ phase transition of poly(vinylidene fluoride) (PVDF), resulting in an extremely slow transition rate.
