A one pot room temperature synthesis of thionyl tetrafluoride (SOF) from elemental fluorine (F) and thionyl fluoride (SOF) is reported. The selective decagram scale process (100 mmol) allows a quantitative preparation of SOF with high purity. The solid-state structure has also been elucidated and compared with the reported gas phase one. The use of this reagent for the formation of the emerging pentafluorooxosulfate [cat][OSF] anions led to the preparation of multiple ion-pairs (cat=Ag, NEtMe, PPN, PPh) in different organic solvents. The SuFEx reservoir ability of this anion was studied and by tuning the solvent system, the reactivity of pure thionyl tetrafluoride was observed using Ag[OSF] in THF and acetone.

Sulfur(VI) Fluoride Exchange (SuFEx) chemistry stands as a well-established method for swiftly constructing complex molecules in a modular fashion. An especially promising segment of this toolbox is reserved for multidimensional SuFEx hubs: three or more substituents pluggable into a singular S centre to make 'beyond-linear' clicked constructions. Sulfurimidoyl difluorides (RNSOF) stand out as the prime example of this, however their preparation from the scarcely available thionyl tetrafluoride (SOF) limits this chemistry to only a few laboratories with access to this gas.

Linkage chemistry and functional molecules derived from the stereogenic sulfur(VI) centre have important applications in organic synthesis, bioconjugation, drug discovery, agrochemicals and polymeric materials. However, existing approaches for the preparation of optically active S(VI)-centred compounds heavily rely on synthetic chiral S(IV) pools, and the reported linkers of S(VI) lack stereocontrol. A modular assembly method, involving sequential ligand exchange at the S(VI) centre with precise control of enantioselectivity, is appealing but remains elusive.

Sulfur(VI) fluoride exchange (SuFEx) is a category of click chemistry that enables covalent linking of modular units through sulfur(VI) connective hubs. The efficiency of SuFEx and the stability of the resulting bonds have led to polymer chemistry applications. Now, we report the SuFEx click chemistry synthesis of several structurally diverse SOF-derived copolymers based on the polymerization of bis(iminosulfur oxydifluorides) and bis(aryl silyl ethers).

Sulfuryl fluoride (SOF) plays an important role in the operation of gas-insulated switchgear (GIS) equipment where it is widely used as the characteristic gas for discharge diagnostics. However, the formation mechanism of SOF is currently unclear, and as a consequence, we have employed a range of methods to investigate the hydrolysis reaction of SOF that is known to afford SOF in the gas phase. These results suggest that two HO molecules are incorporated into a low energy transition state to afford an H-bond network that facilitates proton transfer during the hydrolysis of SOF.
