Inexpensive NaX (X = I, Br, Cl) as a halogen donor in the practical Ag/Cu-mediated decarboxylative halogenation of aryl carboxylic acids under aerobic conditions was written by Fu, Zhengjiang;Jiang, Ligao;Zuo, Qianming;Li, Zhaojie;Liu, Yanzhu;Wei, Zhenhong;Cai, Hu. And the article was included in Organic & Biomolecular Chemistry in 2018.Application In Synthesis of 4-Chloro-2-iodo-1-nitrobenzene This article mentions the following:
A series of aryl halides RX [R = 2-O2NC6H4, 2-NO2-4-MeOC6H3, 3-chlorothiophen-2-yl, etc.; X = Cl, Br, I] was synthesized via Ag/Cu-mediated decarboxylative halogenation of aryl carboxylic acids using sodium halides as halogen donor under aerobic conditions was reported. The halodecarboxylation was shown to be an effective strategy for S-containing heteroaromatic carboxylic acid and benzoic acids with nitro, chloro and methoxyl substituents at the ortho position. A gram-scale reaction and a three-step procedure to synthesize iniparib was performed to evaluate the practicality of this protocol. A preliminary mechanistic investigation indicated that Cu plays a vital role and a radical pathway was involved in the transformation. In the experiment, the researchers used many compounds, for example, 4-Chloro-2-iodo-1-nitrobenzene (cas: 160938-18-1Application In Synthesis of 4-Chloro-2-iodo-1-nitrobenzene).
4-Chloro-2-iodo-1-nitrobenzene (cas: 160938-18-1) belongs to iodide derivatives. Typical reactions of alkyl iodides include nucleophilic substitution, elimination, reduction, and the formation of organometallics. Iodo alkanes participate in a variety of organic synthesis reactions, which include the Simmons–Smith reaction (cyclopropanation using iodomethane), Williamson ether synthesis, Wittig reaction, Grignard reaction, alkyl coupling reactions, and Wurtz reaction.Application In Synthesis of 4-Chloro-2-iodo-1-nitrobenzene
