Iodofluorination of Alkenes Using IF5-Pyridine-HF

Iodofluorination of alkenes was performed by using IF5-pyridine-HF and a reductant such as potassium iodide or tin powder. The addition of IF to the double bond proceeded with stereo- and regioselectivity. In the reaction with internal alkenes,

Silver Fluoride Supported on Calcium Fluoride. Improved Fluorination and Halofluorination Reactions

Silver fluoride dispersed on the surface of calcium fluoride shows improved fluoride nucleophilicity for halogen exchange and addition to alkenes.

Halofluorination of alkenes mediated by 1,1,3,3,3-pentafluoropropene- diethylamine adduct

1,1,3,3,3-Pentafluoropropene-diethylamine complex (PFPDEA) has been found useful as a fluoride source in halofluorination reactions of various olefins. Reactions proceeded with PFPDEA and N-halosuccinimide (NXS, X = Br, I) or 1,3-dibromo-5,5-dimethylhydan

Halofluorination of alkenes using trihaloisocyanuric acids and HF-pyridine

Halofluorination of alkenes with a new system (trihaloisocyanuric acids and HF-pyridine) results in the formation of vicinal halofluoroalkanes. The reaction is regioselective leading to Markovnikov-oriented products and the halofluorinated adducts follow anti-addition in the case of cyclohexene and 1-methylcyclohexene. Reaction yields range from 67-88%. Georg Thieme Verlag Stuttgart · New York.

Iodofluorination of alkenes and alkynes promoted by iodine and 4-iodotoluene difluoride

It was found that a mixture of molecular iodine and 4-iodotoluene difluoride are useful to generate in situ the couple 'IF' that was able to add in a Markovnikov fashion and with prevalent anti-stereoselectivity to various alkenes and alkynes.

Fluorination with ionic liquid EMIMF(HF)2.3 as mild HF source

Hydrogen fluoride is a basic fluorinating reagent, but handling it is difficult. For this reason, some modified fluorinating reagents such as HF-pyridine, Et3N-HF, and poly(hydrogen fluoride) complex have been developed. Those reagents, however, still require aqueous work-up procedures which generate hydrogen fluoride. Recently, ionic liquids have received much attention because of the ease in handling them and the possibility of non-aqueous work-up. An ionic liquid, 3-ethyl-1-methyimidazolium oligo hydrogen fluoride (EMIMF(HF)2.3), which is stable in air and moisture, can be used as a hydrogen fluoride equivalent for some fluorination reactions; it does not require an aqueous work-up.

A mild method for halofluorination of alkenes with ionic liquid EMIMF(HF)2.3

Halofluorination of alkene in the presence of N-halosuccinimide and ionic liquid, 3-ethyl-1-methyl-imidazorium oligo hydrogen fluoride (EMIMF(HF) 2.3), as a HF source was demonstrated. Various alkenes were converted into β-halo organofluorides

Iodofluorination of alkenes and alkyne using electrochemically generated iodonium cation

Iodofluorination reaction of alkenes and alkynes using the iodonium ion electrochemically generated in situ from the iodide anion was carried out. The reaction proceeds at room temperature to provide iodofluorination products regioselectively.
