Fluoroselenylation of acetylenes with xenon difluoride-diorganyl diselenides and xenon difluoride-phenylseleno(trialkyl)silanes

A new, efficient method of fluoroselenenylation of terminal, and open-chain symmetric and unsymmetric disubstituted acetylenes and cycloalkynes, gives vicinal (E)-fluoroalkenyl selenides in moderate to high yields by addition of selenenyl fluoride equivalents. These are formed in situ from xenon difluoride and diaryl, dibenzyl or primary and secondary dialkyl diselenides. Alternatively, the benzeneselenenyl fluoride equivalent is formed by treatment of more reactive phenylselenotrialkylsilanes with xenon difluoride. The regiochemistry of the addition is strongly dependent on the steric effects of substituents bonded to the acetylene.

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.
