Abstract
A new greener protocol that includes the rapid and quantitative conversion of diaryl diselenides, bearing an amido function, to corresponding N-substituted benzisoselenazolones by 254 nm wavelength UV lamp irradiation is presented. This free radical Se-N bond formation was utilized for a series of diversified substrates under mild reaction conditions. Carrying out the process in an photochemically inactive solvent like acetonitrile enabled to obtain a quantitative conversion for both N-aliphatic and N-aromatic derivatives.
