Many alkyl nitrites are thermally unstable and may readily decompose or explode on heating [1]. Methyl nitrite explodes more violently than ethyl nitrite [2]. Lower alkyl nitrites have been known to decompose and burst the container, even in refrigerated storage [3].

Photochemically induced epoxidation of tetrafluoroethene by oxygen with improved yields (71-76%, conversion 21-62%) is achieved in the presence of radical generators such as tri-bromofluoromethane, 1,2-dibromotctrafluorocthane, ethyl nitrite or 1 H, /F,5//-octafluoropen-tyl nitrite.36 The oxidation of tetrafluoroethene with oxygen can also be catalyzed with bis(trifluoromethyl)diazene an undistillable viscous oil with peroxide composition is formed initially which can be quantitatively converted into carbonyl fluoride when heated.37-38...

ACIDO SALICILICO (Spanish) (69-72-7) Combustible solid (flash point 315°F/157°C). Dust or powder forms explosive mixture in air. Reacts with strong oxidizers, ethyl nitrite, iodine, iron salts, lead diacetate. Incompatible with sulfuric acid, alkalis, ammonia, aliphatic amines, alkanolamines, isocyanates, alkylene oxides, epichlorohydrin. Flow or agitation of substance may generate electrostatic charges due to low conductivity. 

ETHYL NITRITE or ETHYL NITRITE SOLUTION (109-95-5) Thermally unstable. Heat around or above 190 F/88°C can cause explosive decomposition (may not need air or oxygen). Decomposes in air, sunlight, or moisture. Forms explosive mixture with air (flash point —31°F/—35°C). A powerful oxidizer. Violent reaction with acids, acid fumes, amines, ammonia, cyanides, reducing agents, other strong oxidizers, salts. 

Methyl y-(l-oxo-l,2,3,4-tetrahydro-2-naphthyl)butyrate added with stirring at —15 to —12° to a soln. of Na in abs. ethanol, then 2.25 moles of ethyl nitrite distilled slowly into the mixture, after an additional 30 min. at —15° kept 12 hrs. in a refrigerator under anhydrous conditions, then stirred slowly with cooling into coned. HGl, and the product isolated within 30 min. ethyl 7-(2-carbethoxyphenyl)-5-oxoheptanoate. Y 81%. F. e. s. I. Ugi, R. Huisgen, and D. Pawellek, A. Ul, 63, 71 (1961). 

An ice-cold ethereal soln. of a-mercaptophenylacetic acid, ethyl nitrite, and a catalytic amount of coned. H2SO4 treated with 2 moles dicyclohexylcarbodiimide -> 4-phenyl-l,3,2-oxathiazolium 5-oxide. Y 87-90%. F. e. s. H. Gotthardt, Tetrah. Let. 1971, 1277 B. 105, 188 (1972). 

Ethyl nitrite poured on trityl mercaptan (under a Ng-atmosphere, which is kept up throughout the entire operation) at 15°, gently shaken, excess ethyl nitrite allowed to evaporate at room temp., and the resulting ethanol removed in vacuo crude triphenylmethyl thionitrite.

Several approaches to the 1,2,3-triazole core have been published in 2000. Iodobenzene diacetate-mediated oxidation of hydrazones 152 led to fused 1,2,3-triazoloheterocycles 153 <00SC417>. Treatment of oxazolone 154 with iso-pentyl nitrite in the presence of acetic acid gave 1,2,3-triazole 155, a precursor to 3-(W-l,2,3-triazolyl)-substituted a,P-unsaturated a amino acid derivatives <00SC2863>. Aroyl-substituted ketene aminals 156 reacted with aryl azides to provide polysubstituted 1,23-triazoles 157 <00HC387>. 2-Aryl-2T/,4/f-imidazo[43-d][l,2,3]triazoles 159 were prepared from the reaction of triethyl AM-ethyl-2-methyl-4-nitro-l//-imidazol-5-yl phosphoramidate (158) with aryl isocyanates <00TL9889>.
