The reaction of fluoroalkylated propargyl mesylates with various nucleophiles, such as zinc reagents and enolates derived from 1,3-dicarbonyl compounds, in the presence of a palladium catalyst was investigated in detail. Various zinc reagents participated in the coupling reaction to give the corresponding fluoroalkylated allenes in good yields. When chiral mesylates were employed, the corresponding optically active allenes were obtained without any loss of enantiomeric purity in the reaction. On the other hand, treatment of trifluoromethylated propargyl mesylate with stabilized carbanions derived from methyl acetoacetate, acetylacetone, and diethyl malonate afforded fluorine-containing furan derivatives in moderate to high yields.
