In 2019,Organic Letters included an article by Mishra, Uttam K.; Patel, Kaushalendra; Ramasastry, S. S. V.. Name: Trimethylsulfoxonium iodide. The article was titled 《Synthesis of Cyclopropanoids via Substrate-Based Cyclization Pathways》. The information in the text is summarized as follows:
A series of unexpected reactions triggered by the dimethyloxosulfonium methylide led to the discovery of unconventional approaches for the synthesis of cyclopropa-fused tetralones and indeno-spirocyclopropanes. These highly functionalized structures were further elaborated in one step to privileged scaffolds such as tetralones, indenones, and fluorenones. As a whole, the results presented herein establish new diversity-oriented folding pathways. 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
