The novel sunlight-promoted aerobic synthesis of selenated iminoisobenzofurans or isoindolinones via the regioselective and chemoselective O-cyclization or N-cyclization of olefinic amides and diselenides has been developed. Interestingly, the chemoselectivity is strongly dependent on the use of TFA as the catalyst or Na2CO3 as the base. This high efficiency and sustainable protocol performed well
