Koohgard, Mehdi; Hosseinpour, Zeinab; Sarvestani, Abdollah Masoudi; Hosseini-Sarvari, Mona published an article in 2020, the title of the article was ARS-TiO2 photocatalyzed direct functionalization of sp2 C-H bonds toward thiocyanation and cyclization reactions under visible light.Electric Literature of 2010-06-2 And the article contains the following content:
An ARS-TiO2 photocatalyst has been prepared by a simple method through stirring a mixture of ARS and TiO2 at room temperature in the dark to extend the photocatalytic response of titanium dioxide toward the visible light spectrum. The synergic effect of ARS and TiO2 in the photocatalyst system has catalyzed direct C-H functionalization of sp2 C-H bonds toward thiocyanation and cyclization reactions. Several aromatic and heteroaromatic scaffolds (2-phenylamino-thiazoles I (R = H, 2-Cl, 4-Ph, etc.), phenols R1OH (R1 = Ph, 3-ethylphenyl, 2-formylphenyl, etc.), anilines R2C6H4N(R3)(R4) (R2 = 2-Me, 3-Cl, 3-OMe, etc.; R3 = H, Me, Et, Ph; R4 = H, Me, Et), indoles II (R5 = H, Me; R6 = H, Me; R7 = H, 5-MeO, 6-methoxycarbonyl, 5-Br, 5-Me) and pyrroles such as 1H-pyrrole and 1-methyl-1H-pyrrole) were treated with the ammonium thiocyanate at room temperature Thiocyanation of phenol and synthesis of 2-aminobenzothiazole derivatives III (R8 = Me, I, prop-1-en-2-yl, etc.) under visible light are presented. The experimental process involved the reaction of 4-Phenylthiazol-2-amine(cas: 2010-06-2).Electric Literature of 2010-06-2
