In 2019,Journal of Catalysis included an article by Ji, Wei; Wang, Hao; Li, Cheng-An; Gao, Fei; An, Zhong-Fu; Huang, Ling; Wang, He; Pan, Yue; Zhu, Dun-Ru; Wang, Jian-Qiang; Guo, Cheng; Mayoral, Jose A.; Jing, Su. Quality Control of 1-Chloro-3-iodobenzene. The article was titled 《Cuprous cluster as effective single-molecule metallaphotocatalyst in white light-driven C-H arylation》. The information in the text is summarized as follows:
This study investigated a series of ferrocenyltelluroether based cuprous halide clusters as effective single-mol. metallaphotocatalysts (SMP) in white light-driven C-H arylation at room temperature and air. A systematic mechanistic study reveals that Cu(I) cluster can be irradiated by visible light to promote proton-coupled electron transfer (PCET), during which the electron from Cu(I)* leaves together with the proton from benzothiazole C-H, leading to the formation of benzothiazolate-coordinated Cu(II) intermediate and aryl radical. Subsequently, the electron transfer (ET) from the ferrocene unit to the Cu(II) center releases the reactive benzothiazolate to form the target product with aryl radical. The advantages of these copper(I) halide clusters as SMP include high photocatalytic efficiency, structure adjustability, mild reaction conditions and good functional group tolerance. In the experimental materials used by the author, we found 1-Chloro-3-iodobenzene(cas: 625-99-0Quality Control of 1-Chloro-3-iodobenzene)
1-Chloro-3-iodobenzene(cas: 625-99-0) belongs to organic iodides. The carbon-iodine bond is weaker than other carbon-halogen bonds due to the poor electronegative nature of the iodine atom. Quality Control of 1-Chloro-3-iodobenzene Organic iodides can be alkyl, alkenyl, or alkynyl, and all of them are very reactive toward with many kinds of nucleophiles.
