, p. 70 - 74 (1994)
2-Nitro-1,3-dicarbonyl and α-nitromonocarbonyl compounds were synthesized in the yields variyng from moderate (30percent) to nearly quantitative by the nitration of β-dicarbonyl compounds in a two-phase system: sulfuric/nitric acid mixture - chloroform at -10 - 10 deg C.The use of phase transfer conditions made it possible to avoid the formation of furoxans as by-products and to simplify the isolation of products.This method is quite common for preparing various α-functional nitro compounds including those containing a CF3-group. - Key words: nitration, α-functional nitro compounds.
A high density pyrazolo-triazine explosive (PTX)
Schulze,Scott,Chavez
, p. 17963 - 17965 (2015)
The fused-ring heterocycle 4-amino-3,7,8-trinitropyrazolo-[5,1-c][1,2,4]triazine (PTX) has promising explosive properties. The Cheetah thermochemical code used its calculated standard enthalpy of formation and its measured crystal density of 1.946 g cm-3 to predict HMX-like explosive performance, while measurements of its thermal stability, sensitivity to impact, friction, and spark showed greater safety margins.
Nitroacetonitrile and Its Synthetic Equivalents
Iwai, Kento,Nishiwaki, Nagatoshi
, p. 13177 - 13185 (2021)
Nitroacetonitrile (NAN) serves as a cyano(nitro)methylating agent facilitating the construction of polyfunctionalized compounds; however, its explosive property is a significant drawback in terms of practical handling. Alkali metal salts of NAN are therma
Development of a safely handleable synthetic equivalent of cyanonitrile oxide by 1,3-dipolar cycloaddition of nitroacetonitrile

Dianionic cyano-aci-nitroacetate affords 3-cyanoisoxazol(in)es upon heating with a range of dipolarophiles in the presence of hydrochloric acid. In this reaction, nitroacetonitrile is formed as an intermediate active species, which serves as a synthetic e
