《Transition-Metal-Free Synthesis of Phenanthridinones through Visible-Light-Driven Oxidative C-H Amidation》 was written by Usami, Kaoru; Yamaguchi, Eiji; Tada, Norihiro; Itoh, Akichika. Quality Control of 2-Iodobenzoic acid And the article was included in European Journal of Organic Chemistry in 2020. The article conveys some information:
The treatment of N-aryl biphenylcarboxamide 2-(4-R2C6H4)-4-R1C6H3C(O)NHR (R = Me, Ph, 1,3-benzothiazol-2-yl, etc.; R1 = H, Br, phenyl; R2 = H, OMe, tert-Bu, Ph, trifluoromethyl, Cl), 1-chloroanthraquinone (1-Cl-AQN) catalyst, and K2CO3 in CHCl3 under visible light irradiation affords phenanthridinone I via radical cyclization. This reaction proceeds under transition-metal-free condition, room temperature, and direct C-H amidation. Mechanistic studies indicate that amidyl radical generation proceeds by visible light induced proton coupled electron transfer (PCET) from N-H bond of the amide. The results came from multiple reactions, including the reaction of 2-Iodobenzoic acid(cas: 88-67-5Quality Control of 2-Iodobenzoic acid)
2-Iodobenzoic acid(cas: 88-67-5) belongs to organic iodides. Generally organic iodides can be divided into two classes of alkyl iodides and aryl iodides. Quality Control of 2-Iodobenzoic acid Typical reactions of alkyl iodides include nucleophilic substitution, elimination, reduction, and the formation of organometallics.
