In 2019,Chemical Communications (Cambridge, United Kingdom) included an article by Shiino, Keisuke; Miyake, Junpei; Miyatake, Kenji. Synthetic Route of C6H4ClI. The article was titled 《Highly stable polyphenylene ionomer membranes from dichlorobiphenyls》. The information in the text is summarized as follows:
A simple, cost-effective synthetic strategy for highly stable, proton conductive polyphenylene membranes is reported. The title polyphenylene ionomer (SPP-BP) is easily prepared from dichlorobenzenesulfonic acid and dichlorobiphenyls. The SPP-BP membrane with an optimized m-biphenylene/p-biphenylene ratio (i.e., 4 : 1) for a hydrophobic moiety exhibits outstanding chem. stability as well as high proton conductivity In the part of experimental materials, we found many familiar compounds, such as 1-Chloro-3-iodobenzene(cas: 625-99-0Synthetic Route of C6H4ClI)
1-Chloro-3-iodobenzene(cas: 625-99-0) belongs to organic iodides.Synthetic Route of C6H4ClI The carbon-iodine bond is weaker than other carbon-halogen bonds due to the poor electronegative nature of the iodine atom. In general, organic iodides are light-sensitive and turn yellow during storage, owing to the formation of iodine.
