Abstract : New routes to fluorinated acetylenes were developed based on additions of iodofluorocarbons to silylacetylenes. Free radical addition of, -diiodo-perfluoroalkanes to trimethylsilylacetylene gave the iodotrimethylsilylolefins, Me3SiIC=Ch(CF2)nCH=CISiMe3, which reacted with potassium t-butoxide or DBU to give the trimethylsilylacetylenes, and with an excess of the base, the free diacetylenes. Perfluoroalkyl iodides similarly gave perfluoroalkyl acetylenes. (Author)
