Tetrafluoroallene has been prepared in 72percent-75percent yield by metallation of either 2-hydropentafluoropropene or 2-bromopentafluoropropene with t-butyllithium followed by thermal elimination of lithium fluoride from the 2-lithiopentafluoropropene.The 2-bromopentafluoropropene route gives the allene free of isobutane. - Keywords: Allenes; Lithium reagents; Metallation reactions; Elimination reactions; IR spectroscopy
