The chemistry of tetrafluoroallene: nucleophilic addition reactions with phenols and amines

Treatment of tetrafluoroallene or its precursor, ICF2CH2CF2I, with phenols in the presence of K2CO3 gave the corresponding unsaturated ethers. Tetrafluoroallene also reacted readily with amines in THF at room temperature to afford 3,3,3-trifluoropropionamides.
