《A new approach to large scale production of dimethyl sulfone: a promising and strong recyclable solvent for ligand-free Cu-catalyzed C-C cross-coupling reactions》 was published in Green Chemistry in 2020. These research results belong to Cheng, Shen; Wei, Wei; Zhang, Xingyu; Yu, Hewei; Huang, Mingming; Kazemnejadi, Milad. Name: 1-Iodonaphthalene The article mentions the following:
Di-Me sulfone (DMSN) was easily prepared through efficient oxidation of DMSO (DMSO) and used as a strong and green solvent for organic reactions. A mixture of HNO3/NaOCl was used as an oxidizing agent for efficient oxidation of DMSO to DMSN. The effect of DMSN was evaluated for copper-catalyzed coupling reactions. It is worth noting that DMSN could play the role of a ligand for copper ions. A general survey was accomplished for various types of C-C cross-coupling reactions catalyzed by CuI in DMSN in the absence of any ligand. Moderate to good yields were achieved for Sonogashira, Heck, and Suzuki cross-coupling reactions. Finally, DMSN was recovered and reused for several consecutive runs without any loss of its activity. The experimental process involved the reaction of 1-Iodonaphthalene(cas: 90-14-2Name: 1-Iodonaphthalene)
1-Iodonaphthalene(cas: 90-14-2) is one of organic iodides. Alkyl iodides react at a faster rate than alkyl fluorides due to the weak C-I bond. Iodo alkanes participate in a variety of organic synthesis reactions, which include the SimmonsSmith reaction (cyclopropanation using iodomethane), Williamson ether synthesis, Wittig reaction, Grignard reaction, alkyl coupling reactions, and Wurtz reaction.Name: 1-Iodonaphthalene
