A clean and selective radical homocoupling employing carboxylic acids with titania photoredox catalysis

A titania photoredox catalysis protocol was developed for the homocoupling of C-centered radicals derived from carboxylic acids. Intermolecular reactions were generally efficient and selective, furnishing the desired dimers in good yields under mild neutral conditions. Selective cross-coupling with two acids proved unsuccessful. An intra-molecular adaptation enabled macrocycles to be prepared, albeit in modest yields. (Chemical Equation Presented).

The vicinal F-C-C-F moiety as a tool for influencing peptide conformation

Diastereoisomers of bis(amino acid amides) of 2,3-difluorosuccinic acid have been prepared and the erythro- and threoisomers display very different conformations. The Royal Society of Chemistry 2005.

Rearrangements accompanying fluorination of 2-amino alcohols and 1,2-diols with Deoxo-Fluor

2-Amino alcohols and 1,2-diols treated with Deoxo-Fluor in methylene chloride resulted in the formation of rearranged major products concomitantly with minor amounts of the straightforward fluorinated replacement products in good yields.

Rearrangement of phenylethenes on reaction with iodine-xenon difluoride

(matrix presented) Phenyl-substituted ethenes react with iodine and xenon difluoride to provide difluorinated products. Iodofluoro intermediates react with xenon difluoride to produce transient iodine difluoride species that lose IF and F- and produce carbocations.

Utility of silicon tetrafluoride as a catalyst of reactions with xenon difluoride: Fluorinations of phenyl alkenes and benzaldehydes

Application of silicon tetrafluoride to fluorinations with xenon difluoride as a catalyst is investigated. It was found that vic-difluorination of phenyl alkenes and transformation of benzaldehydes to difluoromethoxybenzenes using xenon difluoride are enhanced by silicon tetrafluoride.

Hexafluoropropene oxide - a fluorinating reagent for the formation of element-fluorine bonds

Hexafluoropropene oxide (HFPO) is shown to be a good reagent for the nucleophilic formation of the element-fluorine bond in organoelement compounds. Fluorides of Bi, Sb, Se, Te and I were prepared from appropriate oxygen compounds.

Fluorination of olefins with PhSeF3, PhSeF5 and PhTeF5

Phenyselenium trifluoride, PhSeF3 (PSTF) either oxidatively difluorinates or selenofluorinates olefins, depending on their structures. The pentafluorides PhSeF5 and PhTeF5 appear to be effective difluorinating reagents, af

Phenyltetrafluorotelluromethoxide - A new fluorinating reagent for olefins

Phenyltetrafluorotelluromethoxide fluorinates olefins to form 1,2-difluorides. The reaction with styrene afforded 1-fluoro-4-phenyl-1,2-dihydronaphthalene as the main product.

FLUORINATING PROPERTIES OF PhTeF5 AND PhSeF5 TOWARDS C=C BOND

Phenylselenium pentafluoride and phenyltellurium pentafluoride react with olefins affording appropriate 1,2-difluorides under mild conditions.Key words: Phenylselenium pentafluoride, phenyltellurium pentafluoride, xenon difluoride, olefins, difluorination, electrophilic addition.

Site-Selective Fluorination of Organic Compounds Using 1-Alkyl-4-fluoro-1,4-diazabicyclooctane Salts (Selectfluor Reagents)

The new "N-F"-type electrophilic reagent family of 1-alkyl-4-fluoro-1,4-diazabicyclooctane salts (derived from elemental fluorine (F2) and 1-alkyl-1,4-diazabicyclooctane salts) has been found to be very effective for the fluorination of a wide variety of organic substrates.These include steroidal enol acetates and silyl enol ethers, phenyl-substituted olefins, sulfides bearing α-H atoms, certain carbanions, and mildly activated aromatic compounds.The products were obtained with good yields and regioselectivity under very mild reaction conditions.
