Improved syntheses of 1-fluoropropadiene and 1,1-difluoropropadiene are presented as is the synthesis of a third reactive allene, 1,1-difluoro-3-methyl-1,2-butadiene.Gram quantities of these highly reactive fluorinated allenes may be prepared conveniently in high yield and purity.All three are reactive dienophiles and cycloadd regiospecifically using their non-fluorine-substituted double bonds.
