Nitration nitryl fluoride

The cr-complexes (iv) are thus the intermediates corresponding to the substitution process of hydrogen exchange. Those for some other substitutions have also been isolated in particular, benzylidyne trifluoride reacts with nitryl fluoride and boron trifluoride at — ioo°C to give a yellow complex. Above — 50 °C the latter decomposes to hydrogen fluoride, boron trifluoride, and an almost quantitative yield of tn-nitrobenzylidyne trifluoride. The latter is the normal product of nitrating benzylidyne trifluoride, and the complex is formulated as...

Nitryl fluoride has been used for the nitration of terminal gem-dinitro compounds to the corresponding 1,1,1-trinitromethyl compounds. ... 

Eremenko and co-workers used nitryl fluoride for the deamination of amines at subambient temperatures in acetonitrile. The same reaction occurs with primary nitramines and their alkali metal salts bis-nitramines react to give the corresponding bis-nitrate esters. 

Other reagents have been used for the direct nitration of amines under nonacidic conditions. Mandel reported the synthesis of methylnitramine, dimethylnitramine and diisopropy-Initramine from the reaction of nitryl fluoride with the parent amine. The presence of an excess of amine appears to be of prime importance given that other reports give the nitrosamine as a major by-product. 

Alkyl lV,lV-dinitramines (154) have been prepared from the reaction of the tetraalkylam-monium salts (155) of primary nitramines with nitryl fluoride in acetonitrile at subambient temperature. The same reaction with the primary nitramine or its alkali metal salts yields the corresponding nitrate ester. Treatment of the ammonium, potassium, or lithium salts of primary nitramines (156) with a solution of nitronium tetrafluoroborate in acetonitrile at subambient temperature yield alkyl iV,iV-dinitramines. ° The same reactions in ether or ester solvents enables the free nitramine to be used. The nitrolysis of A-alkylnitramides (157) and N,N-diacylamines with nitronium tetrafluoroborate in acetonitrile, and the nitration of aliphatic isocyanates with nitronium tetrafluoroborate and nitric acid in acetonitrile, also yield alkyl A,A-dinitramines (154). 

Deville first synthesized dinitrogen pentoxide in 1849 by reacting silver nitrate with chlorine gas. This reaction probably involves the initial formation of nitryl chloride and, accordingly, dinitrogen pentoxide can also be formed from the reaction of nitryl chloride or nitryl fluoride with a metal nitrate. These reactions are more of theoretical interest than of any practical value. 

Nitryl fluoride is an oxidizer in rocket propellants. It also is a fluorinating and nitrating agent in organic synthesis.

On the basis of eqn. (45) it would be expected that nitryl fluoride in sulphuric acid is a nitrating agent (besides also possessing fluorinating and sulpho-fluorinating effects). 

Aluminum powder also forms sensitive explosive mixtures with oxidants such as liquid CI2 and other halogens, N2O4, tetranitromethane, bromates, iodates, NaC103, KCIO3, and other chlorates, NaN03, aqueous nitrates, KCIO4 and other perchlorate salts, nitryl fluoride, ammonium peroxodisulfate, sodium peroxide, zinc peroxide, and other peroxides, red phosphorus, and powdered pol)Ttetrafluoroethylene (PTFE). 

CADMIO (Spanish) or CADMIUM (7440-43-9) Cd Air exposure, especially of powdered form, may cause chemical to self-ignite. Finely divided material reacts violently with strong oxidizers, fused ammonium nitrate, bromine pentafluoride, lithium, nitryl fluoride, phosphorus trichloride, potassium chlorate carbon dioxide + heat, hydrozoic acid (possible explosion), nitric oxide, tellurium. Contact with acid forms explosive hydrogen gas. Contact with hexafluorobenzene forms a heat-sensitive explosive compound. May react with selenium, elemental sulfur, zinc. On small fires, use dry chemical powder (such as Puiple-K-Powder), foam, Halon, or CO2 extinguishers. 

ANTIMONY or ANTIMONY BLACK (7440-36-0) Dust or powder forms explosive mixture with air. Reacts violently with strong oxidizers and acids, especially halogenated acids, producing toxic stibine gas (antimony hydride). Reacts violently with anunonium nitrate, bromine, bromine azide, bromine tri fluoride, bromoazide, chloric acid, chlorine, chlorine monoxide, chlorine trifluoride, dichlorine oxide, disulfur dibromide, fluorine, halogens, iodine, iodine pentafluoride, nitrosyl fluoride, nitryl fluoride, potassium dioxide, potassium nitrate, potassium permanganate, potassium peroxide, sodium nitrate, sodium peroxide. Forms explosive V-chlorodimethylamines with chloric and perchloric acid.
