Chlorine monofluoride is capable of oxidizing a sulfur atom bonded to one or two perfluoroalkyl groups through the addition of two or four fluorine atoms to the sulfur atom, depending on the ratio of the reagents and the reaction temperature. 

Chlorine Dioxide See under Chlorine Oxides Chlorine Fluorides Although in 1891, H. Moissan (cited in Ref 2) easily prepd bromine iodine fluorides by direct action of the corresponding elements, he claimed that it was impossible to obt any chlorine fluoride. Other investigators among them Lebeau(1906, cited in Ref 2) and Ruff Zedner(1909 cited in Ref 2) also tried, but failed. It was not until 1928 that Ruff et al (Ref 3) succeeded in prepg the monocompd Chlorine Monofluoride, C1F, mw 54.46 colorless gas, fr p -154, bp 100.8, d 1.62 at -100° critical temp -14°, Q evapn 2.27 kcal/mol was prepd by action of si moist chlorine on fluorine at RT if the gases are dry they do...

Oxidation of bis(trifluoromethyl) sulfide with commercially obtainable chlorine monofluoride in the absence of solvent yields bis(trifluoromethyl)sulfur difluoride in >90% yield.2,3 Pure bis-(trifluoromethyl)sulfur difluoride is resistant to hydrolysis and is stable in Pyrex glass at 25°C. for extended periods of time. Reaction of bis(trifluoromethyl)sulfur difluoride with anhydrous... 

Greater than equilibrium concentrations of intermediate species have been observed in the combustion products of several reactant systems. Examples are the concentrations of ammonia in the products of the decomposition of hydrazine (32), the concentration of CH4 in ethylene oxide decomposition (33), nitric oxide and ammonia in the products of the reaction of hydrazine and nitrogen tetroxide (34), and chlorine monofluoride in the products of the reaction of hydrazine and chlorine pentafluorlde (35). 

Chlorine monofluoride is a colorless gas that condenses to a very pale yellow liquid. It is prepared by the interaction of chlorine trifluoride and chlorine or by heating chlorine and fluorine together in a 1 1 ratio. It can be used to saturate multiply bonded systems or oxidize coordinatively unsaturated central atoms. Scheme 8 illustrates some types of CIF reactivity. 

Chlorine monofluoride (which is commercially available) acts as a powerful fluorinating and oxidizing agent (e.g. reaction 16.19) oxidative addition to SF4 was shown in Figure... 

TIN or TIN POWDER (7440-31-5) Sn Finely divided material is combustible and forms explosive mixture with air [autoignition temp (dust cloud) 1166°F/630°C]. Contact with moisture in 911 forms tin dioxide. A reducing agent the powder is very reactive. Violent reaction with strong acids, strong oxidizers, ammonium perchlorate, ammonium nitrate, bis-o-azido benzoyl peroxide, bromates, bromine, bromine pentafluoride, bromine trifluoride, bromine azide, cadmium, carbon tetrachloride + water, chlorine, chlorine monofluoride, chlorine nitrate, chlorine pentafluoride, chlorites, copper(II) nitrate, dimethylarsinic acid, fluorine, hydriodic acid, iodine heptafluoride, nitrosyl fluoride, oxygen difluoride, perchlorates, perchloroethylene, potassium dioxide, phosphorus pentoxide, sulfur, sulfur dichloride, turpentine (fire or explosion). 

TIN(II) CHLORIDE (7772-99-8) SnClj A powerful reducing agent. Reacts violently with strong oxidizers, strong alkalis, bromine, bromine trifluoride (ignition), calcium carbide, chlorine, chlorine monofluoride, copper nitrate, ethylene oxide fluorine, hydrogen peroxide, nitrates, potassium, potassium dioxide, sodium, with risk of fire and explosions. Incompatible with calcium acetylide, hydrazine hydrate (forms explosive stannous dihydrazine chloride) metal nitrates. On small fires, use dry chemical powder (such as Purple-K-Powder), alcohol-resistant foam, or COj extinguishers. 

Selenium-Halogen Compounds.—Perfluoroethyl selenium trifluoride is produced, in almost 100% yield, by the reaction of bis(perfluoroethyl) di-selenide with chlorine monofluoride in a 1 6 ratio. Like SeF, CaFgSeFa forms 1 1 adducts with CsF and SbFg which are best formulated as Cs+C2F6SeFi and CgFsSeF SbFi", respectively. CypgSeFs is oxidized by QF, at ambient temperatures, according to the equation ... 

Chlorine monofluoride (which is commercially available) acts as a powerful fluorinating and oxidizing agent (e.g. reaction 17.22) oxidative addition to SF4 was shown in Figure 16.13. It may behave as a fluoride donor (equation 17.23) or as a fluoride acceptor (equation 17.24). The structures of [C12F] (17.9) and [C1F2] (17.10) can be rationalized using the VSEPR model. Iodine monochloride and monobromide are less reactive than CIF, but of importance is the fact that, in polar solvents, ICl is a source of I" " and iodinates aromatic compounds. 

Attempts to prepare simple sulphenyl fluorides from thiolates and fluorine have not been reported, but are unlikely to be successful due to the oxidizing powers of fluorine or chlorine monofluoride causing oxidation of the sulphur(ii)... 

Sulphur.—Compounds Containing Bivalent Sulphur. Attempts to oxidize bistrifluoromethyl sulphide (conveniently prepared by pyrolysis of commercial bistrifiuoromethyl disulphide at 425—435 °C) to either the sulphoxide or the sulphone using the reagents ( i-(n C H4-CO)sOa-100°C, NOjCIO, NOa-u.v., or NOa-Oa-350°C have proved unsuccessful fluorination of the monosulphide with hot argentic or cobaltic fluoride gave trifluoromethyl-sulphur pentafluoride, while bis(trifluoromethyl)sulphur difluoride was formed at low temperatures with fluorine itself. " Bis(trifluoromethyl)-sulphur difluoride and several other bis(perfluoroalkyl)sulphur difluorides, obtained from the corresponding sulphides and chlorine monofluoride (see p. 162), have been converted into bisperfluoroalkyl sulphoxides ...
