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 reactivefluorinated allenes may be prepared conveniently in high yield and purity. All three are reactivedienophiles and cycloadd regiospecifically using their non- fluorine-substituted double bonds.
