Abstract
4-(pentafluorosulfanyl)benzenediazonium tetrafluoroborate salt was synthesized and isolated. The pentafluorosulfanyl salt was examined in a wide assortment of reactions to form novel SF-bearing alkenes, alkynes, and biaryl derivatives using Heck-Matsuda, Sonogashira, and Suzuki coupling protocols. Dediazoniation of the salt furnished the corresponding p-SF—CHX, CHOS(O)(CF)═NSOCF, and p-SF—CH—NTfderivatives. The azide derivative p-SF—CHNentered into click chemistry with phenylacetylenes to furnish the corresponding triazoles. Various SF-bearing alkenes were synthesized by coupling reactions using a metal catalyst. Fluorodediazoniation selectively furnished the fluoro derivative p-SF—CHF. Homolytic dediazoniation gave the unsymmetrical biaryls, thus demonstrating the broad utility of pentafluorosulfanyl diazonium salts as building blocks of SF5-aromatics that are in high demand in many branches of chemistry including biomedicine and materials chemistry.
