摘要：

An iodine-catalyzed versatile and green method for the synthesis of mono- and 2,3-disulfenylindoles was developed. Various indoles reacted with sodium alkyl- and arylsulfinates by using hydrogen peroxide as the oxidizing agent in PEG(400) under microwave conditions. This simple method enabled the rapid synthesis of mono- and 2,3-disulfenylindoles in good to excellent yields under metal-free conditions. Furthermore, this protocol is environmentally friendly, odorless, and operationally easy and can be performed within short reaction times under mild reaction conditions with excellent functional-group tolerance.
