《Synthesis of Sulfonyl Fluorides from Sulfonamides》 was published in European Journal of Organic Chemistry in 2020. These research results belong to Perez-Palau, Marina; Cornella, Josep. Synthetic Route of C7H9NO2S The article mentions the following:
Aryl sulfonyl fluorides and selected alkylsulfonyl fluorides were prepared chemoselectively from the corresponding sulfonamides by treatment with pyrylium tetrafluoroborate, MgCl2, and KF in MeCN followed by quenching with H2O. Functionalized sulfonamides and sulfonamides derived from pharmaceutical agents underwent deamination and fluorination to sulfonyl fluorides. In the part of experimental materials, we found many familiar compounds, such as 4-Methylbenzenesulfonamide(cas: 70-55-3Synthetic Route of C7H9NO2S)
4-Methylbenzenesulfonamide(cas: 70-55-3) belongs to anime. Left-handed and right-handed forms (mirror-image configurations, known as optical isomers or enantiomers) are possible when all the substituents on the central nitrogen atom are different (i.e., the nitrogen is chiral). With amines, there is extremely rapid inversion in which the two configurations are interconverted.Synthetic Route of C7H9NO2S
