Nitrosyl chloride fluoride

Nitrosyl chloride (178), nitrosyl chloride—hydrogen fluoride (NOF -3HF, NOF -6HF) (179), nitrous acid—hydrogen fluoride solutions (180,181), or nitrogen trioxide (prepared in situ from nitric oxide and oxygen) (27) can be used in place of sodium nitrite in the dia2oti2ation step. [Pg.322]

Mechanism The reaction of and A -steroids with nitrosyl fluoride to form ni trimines is best discussed in conjunction with the nitrosyl chloride reaction leading tothe5a-chloro-6 -nitro steroids (33). Since nitroso alkanes are oxidized with nitrosyl chloride to nitro alkanes it is believed that 5a-chloro-6j5-nitro steroids are formed in this way from an initially formed 5a-chloro-6 -nitroso adduct. The same is true for nitrosyl fluoride up to the stage of the nitroso fluoride (56). Since NOF is a weaker oxidizing agent than NOCl the nitroso fluoride tautomerizes to the fluoro oxime (57) at a rate... [Pg.483]

Fluorinated olefins react with nitrosyl fluoride [131], dinitrogen tetroxide and fluoride ion [131], or nitrosyl chloride and fluoride ion [19S, 199] (equations 35 and 36) to afford fluoronitioso compounds Tertiary fluoroniUoso compounds are a convenient source of tertiary perfluoroalcohols...

Nitrosyl fluoride, NOF, and nitrosyl chloride, NOC1. are quite stable, but the bromide decomposes at room temperature. They are prepared by direct union of NO and the halogen, among other methods. Three tnhalides, NFi, NCI3, and NI3, are known. The first is a colorless stable gas NClj is a yellow liquid and NI3l a brown solid both are explosive. The contrast in... [Pg.1084]

Bromides and iodides give rise to the free halogens, which yield colourless solutions with sodium hydroxide if the ratio of iodide to chloride exceeds 1 15, the chromyl chloride formation is largely prevented and chlorine is evolved.J Fluorides give rise to the volatile chromyl fluoride, Cr02F2, which is decomposed by water, and hence should be absent or removed. Nitrites and nitrates interfere, as nitrosyl chloride may be formed. Chlorates must, of course, be absent. [Pg.326]

Storage of nitrosyl fluoride in the glass reaction vessel containing KF is possible for a few days however, the use of an inert-metal vessel containing anhydrous KF is preferred for an extended period of time. Nitrosyl chloride is stable at room temperatxure but will always contain a small amount of NO and CU because of its reversible decomposition of 0.5%. The reversible decomposition of nitrosyl bromide is appreciable enough at room temperature (7 %) to require storage at a lower temperature, or the gas can be prepared immediately prior to use. ...

Nitrosyl fluoride is useful in the preparation of tiifluoroamine oxide, FiNO, and for storing many volatile Lewis acids as stable solid adducts. Nitrosyl chloride tends to form addition compounds with metal chlorides. The nitrosyl halides are powerful oxidizing agents and are good nitrosylating agents. [Pg.195]
