摘要：

A simple, efficient and expeditious method for synthesis of 2-arylbenzo[b]furans and 2-ferrocenylbenzo[b] furans from readily prepared propargylic alcohols, o-iodophenols and silica gel with the catalyst of PdCl(2)(PPh(3))(2) (2 mol%)/CuI (2 mol%) and microwave-promoted Sonogashira coupling/cyclization reaction is developed. The methodology can produce good to excellent yields. In addition, this method can also be completed in one-pot with iodobenzene, 2-methyl-3-butyn-2-ol and 2-iodo-4-methylphenol as reactants.
