Iron(III)-Catalyzed Dehydration C(sp(2))-C(sp(2)) Coupling of Tertiary Propargyl Alcohols and alpha-Oxo Ketene Dithioacetals: A New Route to gem-Bis(alkylthio)-Substituted Vinylallenes

[摘要]：A new and efficient synthetic approach to [gem-bis(alkylthio)vinyl]allenes has been developed involving iron(III)-catalyzed dehydration C(sp(2))-C(sp(2)) coupling of tertiary propargyl alcohols and alpha-oxo ketene dithioacetals, affording a variety of [gem-bis(alkylthio)vinyl]allenes in good to excellent yields.
