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... 

Nitrosyl chloride [55], nitrosyl fluoride-hydrogen fluoride liquid complexes (NOF3HF, NOF 6HF) [56], nitrous acid-hydrogen fluoride solutions [57, 5 ] nitrogen trioxide (prepared in situ from nitric oxide and oxygen) [59] and rert-butyl nitrite-hydrogen fluoride-pyndine [60] have been substituted for sodium nitrite in the diazotization step... 

Nitrosonium tetrafluoroborate has been prepared from nitrosyl fluoride (NOF) and boron trifluoride in Freon-113. With this reagent, in a nitro-methane solution, pyridine was converted into jV-nitrosopyridinium tetra-fluorobate, m.p. 155°-158°C [33]. 

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... 

The simplest oxide fluorides of nitrogen, nitrosyl fluoride (NOF) and nitryl fluoride (N02F), were first prepared in 1905 and 1932, respectively, yet their chemistry was not studied in detail until the early 1960s when they were recognized as potential rocket propellants. The oxide fluorides of nitrogen were reviewed in 1965 and 1968 by Woolf (38) and Schmutzler (39), respectively, and their physical and chemical properties were also summarized by Kuznetsova (40). 

Finally, the following reaction of nitrosyl fluoride, NOF, with C1F is noteworthy ... 

Nitrosyl fluoride, NOF, is used as an oxidizer in rocket fuels.
