[(PhCH2O)2P(CH3)2CHNCH(CH3)2]2PdCl2/CuI as Cocatalyst for Coupling-Cyclization of 2-Iodophenol with Terminal Alkynes in Water

[(PhCH2O)2P(CH3)2CHNCH(CH3)2]2PdCl2/CuI as Cocatalyst for Coupling-Cyclization of 2-Iodophenol with Terminal Alkynes in Water

A new and efficient [(PhCH2O)2P(CH3)2CHNCH(CH3)2]2PdCl2/CuI-co-catalyzed coupling-cyclization reactions of 2-iodophenol with terminal alkynes is described. Different 2-substitued benzo[b]furan derivatives are obtained in good to excellent yields. This protocol employs a relatively low palladium(II)...

Zusammenfassung:A new and efficient [(PhCH2O)2P(CH3)2CHNCH(CH3)2]2PdCl2/CuI-co-catalyzed coupling-cyclization reactions of 2-iodophenol with terminal alkynes is described. Different 2-substitued benzo[b]furan derivatives are obtained in good to excellent yields. This protocol employs a relatively low palladium(II) catalyst loading in water under air conditions.
