Although thionyl tetrafluoride and pentafluorosulfur hypofluorite can be prepared by fluorination in a flow reactor, the procedures described here are performed in a static system. This method offers several advantages. The metal equipment needed is commercially available, and the ability to closely control the stoichiometry of the reactions results in the formation of the products in high purity. However, the amount of material that can be prepared in one run is limited. Thionyl tetrafluoride may also be prepared in good yield by the oxidation of sulfur tetrafluoride. This method is also easy to carry out if the requisite high-pressure equipment is available. 

Treatment of thietane with chlorine, bromine,or sulfuryl chloride yields ring-opened materials. Trifluoromethyl hypofluorite gives tetravalent and hexa-valent sulfur-fluorine compounds 86 (a sulfurane) and 87 (a persulfurane) from thietane and 3-methylthietane. Ionization of 86 (R = H) at —20° to — 40°C was indicated by the collapse of the two doublets observed in the F nmr spec-... 

FLUORINATION Acetyl hypofluorite. Cesium fluoroxysulfate. (Diethylamino)-sulfur trifluoride. 

Trifluoromethyl hypofluorite reacts with mercury at room temperature to afford COFj and HgjFj [1648]. Lithium reacts similarly, but more slowly at the same temperature, giving COFj and lithium fluoride. With sulfur, both COFj and SF are produced according to the stoicheiometry [1648] ... 

SULFUR HYDRIDE (7783-06-4) A highly flammable and reactive gas. Violent reaction with strong oxidizers, metal oxides, metal dusts and powders, bromine pentafluoride, chlorine trifluoride, chromium trioxide, chromyl chloride, dichlorine oxide, nitrogen trichloride, nitryl hypofluorite, oxygen difluoride, perchloryl fluoride, phospham, phosphorus persulfide, silver fulminate, soda-lime, sodium peroxide. Incompatible with acetaldehyde, chlorine monoxide, chromic acid, chromic anhydride, copper, nitric acid, phenyldiazoniumchloride, sodium. Forms explosive material with benzenediazonium salts. Attacks many metals. Flow or agitation of substance may generate electrostatic charges due to low conductivity. 

In 1955 Dudley, working with Cady and Eggers, obtained pentafluorosulfur hypofluorite by the reaction of fluorine, in excess, with thionyl fluoride, or sulfur dioxide, at 200° in the presence of copper coated with fluorides of silver (78). It is probable that thionyl tetrafluoride is an intermediate in the process and that it combines with fluorine to give FjSOF. ...
