《Copper-Catalyzed Annulation or Homocoupling of Sulfoxonium Ylides: Synthesis of 2,3-Diaroylquinolines or α,α,β-Tricarbonyl Sulfoxonium Ylides》 was published in Organic Letters in 2020. These research results belong to Zhu, Shuai; Shi, Kai; Zhu, Hao; Jia, Zhe-Kang; Xia, Xiao-Feng; Wang, Dawei; Zou, Liang-Hua. Name: Trimethylsulfoxonium iodide The article mentions the following:
An unprecedented copper-catalyzed reaction of sulfoxonium ylides and anthranils was reported that enabled an easy access to 2,3-diaroylquinolines I [R = H, 6-F, 7-Cl, etc.; R1 = Ph, 2-thiophenyl, 4-MeC6H4, etc.] through a [4+1+1] annulation. Copper-catalyzed homocoupling of sulfoxonium ylides provided α,α,β-tricarbonyl sulfoxonium ylides II, which provided a strategy to extend the carbon chain through C-C bond formation. The utility of the products as well as the mechanistic details of the process were presented. In the part of experimental materials, we found many familiar compounds, such as Trimethylsulfoxonium iodide(cas: 1774-47-6Name: Trimethylsulfoxonium iodide)
Trimethylsulfoxonium iodide(cas: 1774-47-6) is a sulfoxonium salt. It is used to generate dimethyloxosulfonium methylide by reaction with sodium hydride. The latter compound is used as a methylene-transfer reagent, and is used to prepare epoxides.Name: Trimethylsulfoxonium iodide
