(Fluoroimido)tetrafluorosulfur undergoes a number of reactions with strong electrophiles, involving addition to the sulfur-nitrogen double bond. It also reacts readily with fluoride ion, forming the reactive nucleophile SF5NF-. Chlorine(I) fluorosulfate, bromine(I) fluorosulfate, and peroxydisulfuryl difluoride add to F4S=NF, forming the respective cis adducts. The 19F NMR spectra of these adducts provide the first examples of magnetic nonequivalence induced in an octahedral system by an adjacent chiral center. The anion SF5NF-, generated in situ from F4S=NF and KF, reacts readily with Br2, forming SF5NBrF, and with acyl fluorides, forming RCONFSF5. The SF5NP ion also reacts with F2C=NF to form (SF5NF)FC=NF, which is isomerized to the unusual azo compound F5SN=NCF3 in the presence of CsF. Self-reaction of F4S=NF in the presence of KF does not produce the expected dimer (SF5NF)F3S=NF. Instead, extensive decomposition is observed, along with a low yield of the unusual amine (SF5)2NF.
