Owing to their special biological activities, organic selenium heterocyclic compounds have widely applications in organic chemistry and drug synthesis. A series of methods for the synthesis of organoselenide heterocyclic compounds have been reported, however, shortcomings still exist. In this paper, an effective method for the synthesis of 3-aryl(alkyl)selenylcoumarin derivatives via the ICl-catalyzed selenation of coumarins with diaryl(alkyl)diselenide at room temperature is reported. In addition, this method is also suitable for the construction of Csp2Se bonds of other heterocyclic compounds. Compared to previous methods, this method has the advantages of mild conditions and wide functional groups tolerance, providing a general pathway to organoselenide heterocyclic compounds.
