Synthesis of Selenaheterocycles via Visible-Light-Mediated Radical Cyclization

An approach for the synthesis of selenaheterocycles starting from aryl diazonium salts was developed. The one-pot process and subsequent visible-light-mediated silver-catalyzed cyclization enabled the synthesis of selenaheterocycles in the absence of a photocatalyst. The reactions were carried out under mild conditions without the use of toxic or sensitive reagents. (Figure presented.).

Ag-Catalyzed Cyclization of Arylboronic Acids with Elemental Selenium for the Synthesis of Selenaheterocycles

A general method for the synthesis of five-membered and six-membered selenaheterocycles through Ag-catalyzed C?Se bond-forming reaction is reported. This reaction proceeds via intramolecular cyclization of arylboronic acids with selenium powder. Preliminary mechanism studies demonstrate that this transformation involves a selenium-centred radical intermediate. (Figure presented.).
