Phenylselenofluoration d'alcynes

Article abstract of DOI:10.1016/0040-4039(90)80089-5

The electrophilic anti-addition of the elements of benzeneselenenyl fluoride towards carbone-carbone triple bonds is performed by a one-pot reaction of N-phenylselenophthalimide and triethylamine tris-hydrofluoride with disubstituted alkynes ; starting from monosubstituted alkynes, the reaction proceeds further to afford vinylic diselenated compounds after hydrofluoric acid elimination. Some products of mono-addition could be transformed into vinylic or allenic fluorides.
