ChemInform Abstract: Visible‐Light‐Induced Aerobic Thiocyanation of Indoles Using Reusable TiO₂/MoS₂ Nanocomposite Photocatalyst.

Photocatalyzed Facile Synthesis of α-Chloro Aryl Ketones with Polyaniline–g-C3N4–TiO2 Composite under Visible Light

“…Expectedly, no reaction occurred in the presence of anatase TiO 2 (entry 12). Our previously reported MoS 2 −TiO 2 (1:10, molar ratio of Mo to Ti) nanocomposite was also evaluated, 35,36 and only 25% yield of 3aa was obtained (entry 13). Moreover, simply adding the three components PANI, g-C 3 N 4 , and TiO 2 (with the same loadings as entry 2) to the reaction mixture led to a poor yield of 3aa (21%, not shown in Table 1).…”

“…Given the importance of α-chloro aryl ketones, and in continuation of our interest in the design and application of semiconductor photocatalysts, 35,36 herein, we report the preparation of a ternary PANI−g-C 3 N 4 −TiO 2 composite and demonstrate its application in the chemoselective synthesis of α-chloro aryl ketones (Scheme 2).…”
