Abstract
Abstract 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- ...
