Nitrosyl chloride antimonie

Since N-nitrosoimmonium ions seem to be involved in the hydrolysis of a-acetates, it should be possible to isolate such species as stable salts. For this purpose, we selected a system such as XVII in which the phenyl group should provide further stabilization of such a carbonium ion. After the reaction of nitrosyl chloride with the corresponding imines, addition of antimony pentachloride resulted in the precipitation of pale yellow solids these could be isolated and stored under nitrogen for several days at room temperature. ...

HYDROCHLORIC ACID/NITRIC ACID, MIXTURE (8007-56-5) An extremely strong oxidizer. Violent reaction with reducing agents, combustible materials, metal powders, organic substances, and other easily oxidized materials. Reacts with ethylene chloride, sulfuric acid, acrolein, antimony trisulfide, antimony tritelluride, arsenic pentasulfide, 1,1-dichloro-l-nitroethane, 1,3-dichloropropene, diethylamine, s-trioxane. Incompatible with m-bis(trichlormethyl)benzene. Dissolves metals such as gold, palladium, and platinum. Attacks polyvinyl alcohol and engineering metals, including Hastelloy C and 316 stainless steel. See also Hydrochloric Acid, Nitric Acid, Nitrosyl Chloride. 

The ability of chloride to form a chromyl compound is not unique within the halogens. When bromide and iodide are treated with sulfuric acid and dichromate, they are converted into their free halogens. But fluorides will under these conditions form volatile chromyl fluoride, C1O2F2, and therefore give a reaction similar to chloride. The mercury chloride does not respond to the test owing to its low solubility, and the formation of chromyl chloride is limited for lead, silver, antimony, and tin chloride for the same reason. Iodide in 1 15 relative to chloride will give free chlorine. The presence of nitrites and nitrates interferes, as nitrosyl chloride is formed. ... 

The formation of compounds containing complex anions is expected to occur easily in an acceptor solvent such as sulphur dioxide. The formation of K3SbCl6 and KSbCle has been reported . Reactions between nitrosyl chloride, acetyl chloride or benzoyl chloride and antimony(V) chloride lead in liquid sulphur dioxide to the respective chloro-complexes, namely N0[SbCl6], [CH3CO]SbCl6 and [C6H5CO][SbCl6] , but the latter has recently been shown to be Cl... 

Considerable further contributions to the understanding of the chemistry of nitrosyl chloride solutions have been provided by the results of tracer studies o- using 36C1. The exchange was studied between nitrosyl chloride and the dissolved chlorides of aluminium(III), gallium(III), indium(III), thallium (III), iron(III) and antimony(V). Rapid exchange was found and it was concluded that the chlorine... 

Thus chlorine-coordination at the antimony provides a higher stability to the complex species, than oxygen-coordination o. The ligand exchange is easily completed when chloride ions are provided to give hexachloroantimonates, while in their absence either the supposed slight self-ionization of the solvent or the presence of unavoidable impurities, such as hydrated hydrogen chloride, are responsible for the occurrence of the reaction. Formation of a chloro-complex in phosphorus oxychloride is therefore different from that in liquid nitrosyl chloride, because the 0-donor properties of the solvents are vastly different. 

Electrophilic displacement. Account for the fact that nitrosyl chloride, C1N=0, and antimony pentachloride, SbClj, both of which are covalent molecules, react with each other to form a salt.
