propargyldiisopropylamine by the Sonogashira coupling reaction, underwent the allene transformation reaction in the presence of Pd2(dba)3·CHCl3 catalyst (2.5 mol %) and 1,2-bis[bis(pentafluorophenyl)phosphino]ethane (10 mol %) at 100 °C in CHCl3, giving the corresponding heterocyclic allenes in good to high yields via the palladium-catalyzed hydride-transfer reaction.
