Difluoro(aryl)(perfluoroalkyl)-lambda4-sulfanes and Selanes: Missing Links of Trichloroisocyanuric Acid/Potassium Fluoride Chemistry
The TCICA/KF approach to oxidative fluorination of heteroatoms has emerged as a surprisingly simple, safe, and versatile surrogate to classically challenging fluorination reactions. Although polyfluorination (or chlorofluorination) of diaryl disulfides, diaryl diselenides, diaryl ditellurides, aryl iodides, and aryl(perfluoroalkyl)tellanes has been described, the application of this TCICA/KF methodology to aryl(perfluoroalkyl)sulfanes and selanes remains an area of unexplored chemical space. Accordingly, to address the ?missing links? in the developing series of chalcogen-based substrate reactivity, we report mild syntheses of metastable difluoro(aryl)(perfluoroalkyl)-lambda4-sulfanes and selanes. As only limited examples of these species exist in the current literature (accessible only by using F2 or XeF2/HF), we have carried out detailed structural analyses, primarily using NMR and SC-XRD data. In addition, we investigate the effect of the perfluoroalkyl chain on the outcome of oxidative fluorination, and, finally, we provide preliminary evidence that difluoro(aryl)(trifluoro-methyl)-lambda4-sulfanes may act as fluorinating reagents.
We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 652-12-0, and how the biochemistry of the body works.Synthetic Route of 652-12-0
