The use of lithium butyl(phenylthio)cuprate as a reactant with propargylic acetates for the synthesis of terminal allenes is reported. Treatment of propargylic acetates with lithium butyl(phenylthio)cuprate in diethyl ether at - 78°C yields the title compounds on workup with aqueous ammonium chloride.
