Perfluorinated alkynes are potential intermediates for the introduction of perfluoroalkyl chains in organic compounds and have previously been prepared from the corresponding perfluoroalkyl iodides. The lower alkynes RF-CS-H (R, = CF3, C2F5, or i-C3F,) were the first reported,lS2 and their chemistry was later de~eloped.~ Long-chain homologues have been prepared more recently either from bromination, de- hydrobromination, and debromination reaction^,^ or from ...
