Study of anodic fluorination in anhydrous hydrogen fluoride

Journal of Electroanalytical Chemistry, 1980
Abstract The basic features of anodic fluorination were studied by the ring-disc system. The observed current potential behaviour is discussed with regard to the reaction site and the fluorinating agent.

Interfacial tension and fluorine evolution on a carbon anode

Journal of Fluorine Chemistry, 2006
During electrolysis of molten KF-2HF, strongly adherent fluorine bubbles are generated at the surface of carbon anode. The current was passing even if the horizontal anode was fully covered with gas film. The formation and growth of gas bubbles were studied by transient electrochemical techniques.

Selective anodic fluorination of phthalides in ionic liquids

Green Chem., 2003
Anodic fluorination of phthalide and its derivatives was carried out using Et4NF·4HF, Et3N·5HF and imidazolium ionic liquids like 1-ethyl-3-methylimidazolium triflate [emim][OTf]. Despite the high oxidation potential of phthalide, the fluorination proceeded efficiently in ionic liquids (ILs) containing fluoride salts.

Anodic oxidation of olefins in presence of fluorine anion

Bulletin of the Academy of Sciences of the USSR Division of Chemical Science, 1976
1. The anodic oxidation of olefins in the presence of fluorine anion can be accompanied by the addition of two fluorine atoms to the multiple bond. Allylic substitution is a more characteristic reaction in the anodic oxidation of olefins. 2. The high lability of the allylic and benzylic fluorine atoms in acid medium is the reason for the

Diastereoselective fluorination at benzylic position by anodic oxidation

Tetrahedron Letters, 1990
Abstract By anodic oxidation of benzylic derivatives 1 in Et3N,3HF/CH3CN, diastereoselective fluorination in the α position of the electron withdrawing group is obtained. The observed stereoselectivities are discussed in connection with the inductor group. The role of the anode is also examined.

Fluorinated Aromatic Anode‐electrolyte Interface for Highly Reversible Zinc Anode

Advanced Functional Materials
Abstract The issues of dendrite formation and side reactions at the zinc anode–electrolyte interface are the primary factors limiting the reversibility and stability of aqueous zinc‐ion batteries (AZIBs). Herein, the functionalities of fluorinated aromatic additive on zinc anode–electrolyte interface are ...

Anodic partial fluorination of organic molecules. Synthesis of monofluoro β-lactams using anodic fluorination of 4-thiazolidinones as a key step

Journal of Fluorine Chemistry, 1991
Abstract Although anodic perfluorination is a well-established technique, relatively few studies on anodic partial fluorination have been made. As a broad program of anodic partial fluorination of organic molecules, 1) highly regioselective anodic monofluorination of 4-thiazolidinones 1 was achieved.
