Anodic fluorination of some electrophilic alkenes (conjugated with electron-withdrawn groups), ethyl cinnamates, R C 6 H 4 CH CH CO 2 Et (R = H, CH 3, CH 3 O, F and CF 3), cinnamonitrile, C 6 H 4 CH CH CN, phenyl stryryl ketone, and t-butyl styryl ketone using ammonium fluorides as the fluorine source and supporting electrolyte, in CH 2 Cl 2 as electrolytic solvent yields the expected vicinal Cited by: 4. ChemInform Abstract: Electrolytic Partial Fluorination of Organic Compounds. Part Highly Regioselective Anodic Monofluorination of 2-Thiadiazolyl, 2-Oxadiazolyl, and 2-Triazolyl by: Recent developments in regio- and diastereoselective anodic fluorination of heterocyclic compounds including α-amino acid derivatives are described. Marked effects of supporting fluoride salts and solvents on the fluorination are discussed. Synthetic applications of the anodically fluorinated heterocycles . Anodic benzylic fluorination of toluene, ethylbenzene, and cumene derivatives This paper is dedicated to Prof. Hans J. Schäfer of the University of Münster on the occasion of his 65th birthday Author links open overlay panel Toshiki Tajima Hideki Ishii Toshio Fuchigami.

Anodic Fluorination Based on Cation Exchange between Alkali-Metal Fluorides and Solid-Supported Acids. Angewandte Chemie International Edition , 46 (19), Pavel A. Zaikin, Gennady I. Borodkin, in Late-Stage Fluorination of Bioactive Molecules and Biologically-Relevant Substrates, Electrochemical Anodic Fluorination. Electrochemical fluorination seems to be an ideal method for the introduction of fluorine atoms into organic molecules because it can be carried out under mild conditions in a one-step procedure. Electrolytic Partial Fluorination of Organic Compounds. Highly Regioselective Anodic Monofluorination of Oxindole and 3-Oxo-1,2,3,4-tetrahydroisoquinoline Derivatives: Effects of Supporting Fluoride Salts and Anode Materials.   The anodic fluorination of crown ethers resulted in carbon-carbon bond cleavage which led to the selective production of a,o3-difluoro products with high yields. © Elsevier Science Ltd.

The superhydrophobic surface has a great advantage of self-cleaning, inhibiting bacterial adhesion, and enhancing anticoagulant properties in the field of biomedical materials. In this paper, a superhydrophobic surface was successfully prepared on titanium alloy via high-speed micro-milling, anodic oxidation and fluoroalkylsilane modification. This chapter summarizes diastereoselective electrochemical fluorination developed in our laboratory. This includes diastereoselective anodic fluorination of open-chain and cyclic compounds containing heterocyclic compounds mainly via intramolecular 1,2- and 1,3-asymmetric induction. The stereocontrol mechanisms are illustrated. Later, this defluorination behavior was confirmed by the work with an in situ scanning tunneling microscopy (STM) imaging for F-SWNTs with a stoichiometry CF (prepared by a °C fluorination of MER-SWNTs with – nm diameter) and for the sample after defluorination with thermal treatment at °C [8]. The work showed that the. Highly diastereoselective and efficient anodic α-fluorination of phenyl, p-chlorophenyl, and 2-naphthyl 3,3,3-trifluoromethoxypropyl sulfides was successfully carried out at platinum electrodes in Et 3 N-nHF (n = 3–5)/MeCN to provide the corresponding α-fluorinated products in good yields, whereas the corresponding p-methoxyphenyl sulfide derivative gave much lower diastereoselectivity.
