Platinum-catalyzed divergent reactivity of α-hydroxyallenes: Synthesis of dihydrofurans and α,β-unsaturated ketones

Abstract

α-Allenols were catalytically transformed into dihydrofurans in the presence of platinum dichloride. Notably, using platinum dichloride along with silver triflate as the catalytic system, α,β-unsaturated ketones were obtained. Therefore, the role of the silver salt may not just consist in the activation of the platinum precatalyst. Copyright © 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.Peer Reviewe
