Lemir, Ignacio D.; Castro-Godoy, Willber D.; Heredia, Adrian A.; Schmidt, Luciana C.; Arguello, Juan E. published an article in 2019, the title of the article was Metal- and photocatalyst-free synthesis of 3-selenylindoles and asymmetric diarylselenides promoted by visible light.Quality Control of 4-Phenylthiazol-2-amine And the article contains the following content:
A novel and sustainable procedure was developed for the synthesis of 3-selenylindoles I = [R1 = H, Me, H2CCH2CH=CH2; R2 = H, Me; R3 = Me, Ph, Bn, etc.] employing diorganyl diselenides and indoles as starting materials. The methodol. was extended to electron-rich arenes to produce diarylselenides. Visible blue light was used to promote the reaction without employing transition metal complexes or organic photocatalysts as sensitizers. Additives such as strong oxidants or bases were not required. Moreover, ethanol was employed as a benign solvent under mild reaction conditions. Through this easy and eco-friendly approach, several 3-selenylindoles I and a number of asym. diarylselenides Ar1SeR4 [Ar1 = Ph; R4 = 4-N(Me)2C6H4, 2,4,6-(HO)3C6H2, etc.] were obtained in good to excellent isolated yields. The experimental process involved the reaction of 4-Phenylthiazol-2-amine(cas: 2010-06-2).Quality Control of 4-Phenylthiazol-2-amine
