Evaluation of the compatibility of pentafluorosulfanyl chloride with various solvents and additives

摘要

Pentafluorosulfanyl chloride (SF5Cl) is the most prevalent pentafluorosulfanylating agent. However, its compatibility with common solvents has not been evaluated. Thus, in order to provide a qualitative guide for the use of SF5Cl, we report a systematic evaluation of its compatibility in various organic solvents and water via the well-established SF5Cl radical addition on an alkene, using allyl benzyl ether as the model substrate. Solvent and reaction temperature comparison, as well as a robustness screen have been performed and will be discussed.
