A convenient process for the synthesis of 3-arylbenzofurans and their derivatives by 2-phenoxy-1-phenylethanones via TfOH-SiO2 catalyzed is developed. This method provides several advantages such as simple work-up procedure, simple post-treatment process, high yields, broad applicability, practicability, and recycling of the catalyst.
