In 1954,Nippon Kagaku Zasshi included an article by Yamashiro, Seishi; Matsueda, Sumu. Application of 56966-48-4. The article was titled 《Chlorodiphenylene oxides. I. Synthesis of 1,6- and 2,6-dichlorodiphenylene oxides》. The information in the text is summarized as follows:
2,6-Dichlorodiphenylene oxide, m. 149°, has been synthesized from 2,6-diaminodiphenylene oxide sulfate by the Sandmeyer method in 40.5% yield. o-Chlorophenol (25 g.) and 11 g. KOH melted, treated with 37 g. 2,5-Cl2C6H3NO2, and heated 7 hrs. at 170-80° yielded 35 g. 2-nitro-2′,4-dichlorodiphenyl ether (I), m. 62°. I was converted to the corresponding 2-amino compound (II), m. 167° by action of SnCl2-HCl in MeOH in 95% yield. Direct chlorination of II by addition of a CCl4 solution of Cl afforded 1,6-dichlorodiphenylene oxide, m. 135°, 7.7% yield, and 2-hydroxy-2′,4-dichlorodiphenyl ether, m. 66° 7.5% yield. The results came from multiple reactions, including the reaction of 2-Amino-2,4-dichlorodiphenyl ether(cas: 56966-48-4Application of 56966-48-4)
2-Amino-2,4-dichlorodiphenyl ether(cas: 56966-48-4) belongs to anime. Amines have a free lone pair with which they can coordinate to metal centers. Amine–metal bonds are weaker because amines are incapable of backbonding, but they are still important for sensing applications.While stronger than hydrogen bonds, amine–metal bonds are still weaker than both covalent and ionic bonds.Application of 56966-48-4
