ABSTRACT
This study describes the syntheses of 2,3-bis(selanyl)quinoxalines via the photoinduced cyclizations of o-diisocyanoarenes with diaryl or dialkyl diselenides, in addition to providing a detailed discussion of the corresponding mechanism and revealing that the developed procedure can also be applied to prepare 2-thiolated quinoxaline derivatives from o-diisocyanoarenes and thiols. The developed technique does not need the use of additives or metal catalysts and features the advantages of a high conversion, a broad substrate scope, and mild reaction conditions, thereby rendering it a valuable addition to the quinoxaline synthesis toolbox.
