Synthesis of fluoroalkylated alkynes: Via visible-light photocatalysis

Fluoroalkylated alkynes, which are versatile building blocks for the synthesis of various biologically active organofluorine compounds, were synthesized from easily available alkynyl halides and fluoroalkyl halides by visible-light photocatalysis. Addition of fluoroalkyl radicals to alkynes and subsequent dehalogenation selectively yielded fluoroalkylated alkynes.

Oxidative coupling of radicals in reactions of compounds of tervalent iodine with trimethylsilyl(phenyl)acetylene

Reactions of trimethylsilyl(phenyl)acetylene with aryl and alkyl difluoroiodides give coupling products of substituents in high yields.

Perfluoroalkylations of Carbanions with (Perfluoroalkyl)-phenyliodonium Triflates (FITS Reagents)

FITS reagents reacted with primary alkylmagnesium halides in THF at -78 deg C to give the corresponding perfluoroalkyl(Rf)-alkanes in moderate to good yields.But an alkyl-lithium or -copper gave a poor yield of the Rf-product.The rea

PERFLUOROALKYLATION OF CARBANIONS

A successful perfluoroalkylation of various carbanions by the use of perfluoroalkylphenyliodonium trifluoromethanesulfonate (FITS) was described.The reactivity of other perfluoroalkyliodonium salt was also examined.
