And the article was included in Organic Letters in 2015.HPLC of Formula: 1195-14-8 This article mentions the following:
An efficient and practical system for inexpensive bromination and iodination of arenes as well as heteroarenes by using readily available DMSO (DMSO) and HX (X = Br, I) reagents is reported. This mild oxidative system demonstrates a versatile protocol for the synthesis of aryl halides. HX (X = Br, I) are employed as halogenating reagents when combined with DMSO which participates in the present chem. as a mild and inexpensive oxidant. This oxidative system is amenable to late-stage bromination of natural products. The kilogram-scale experiment (>95% yield) shows great potential for industrial application. In the experiment, the researchers used many compounds, for example, 2-Methylbenzo[b]thiophene (cas: 1195-14-8HPLC of Formula: 1195-14-8).
2-Methylbenzo[b]thiophene (cas: 1195-14-8) belongs to benzothiophene derivatives. Benzothiophenes are valuable heterocycles that are widely used in medicines, agrochemicals, and materials science. Due to its aromaticity, thiophenes do not exhibit the same properties as conventional thioethers.HPLC of Formula: 1195-14-8
