MINDO-Forces calculations with complete geometry optimization have been performed on nitromethane, aci-nitromethane and X-substituted nitromethane and aci-nitromethane (X = F, OH, NH2, CH3, CN, CF3, NO2, CHO). It is found that nitromethane is more stable than aci-nitromethane by 9.337 kcal/mol. This agrees with theoretical calculations. Thermodynamically, substituted acinitro tautomers are more...

A patient who ingested a methanol/nitromethane mixture (model airplane fuel) showed an apparent plasma creatinine concentration of 8.0 mmol/L by the Jaffé reaction when the actual creatinine concentration, as measured by a specific enzymatic method, was 0.09 mmol/L. This effect was due to nitromethane in the plasma. Interference by nitromethane with the determination of creatinine by reaction w...

Molecular dynamics simulations have been used to investigate the thermodynamic melting point of the crystalline nitromethane, the melting mechanism of superheated crystalline nitromethane, and the physical properties of crystalline and glassy nitromethane. The maximum superheating and glass transition temperatures of nitromethane are calculated to be 316 and 160 K, respectively, for heating and...

Nitromethane is a potential green monopropellant, but there are limited kinetic studies on its burning behavior in oxygen-free conditions, such as those required byunderwater and space propulsion applications. Mechanisms for nitromethane combustion have generally been validated against experiments oxidative environments. These provide valuable data gas-phase kinetics,but they less informative e...

Activation of the aci-form of nitromethane using Lewis acids for the attack of carbon nucleophiles was studied. 1,3-Dicarbonyl compounds in the presence of catalytic amounts of AuCl(3) or Cu(OTf)(2) in nitromethane solvent could be converted into methylene-bridged bis-1,3-dicarbonyl compounds.

Decay dynamics of nascent dipole bound states of acetonitrile and nitromethane are examined using time-resolved photoelectron imaging of iodide-acetonitrile (I(-)·CH3CN) and iodide-nitromethane (I(-)·CH3NO2) complexes. Dipole-bound anions are created by UV-initiated electron transfer to the molecule of interest from the associated iodide ion at energies just below the vertical detachment energy...

Ion-pair formation in gaseous nitromethane (CH3NO2) induced by electron transfer has been studied by investigating the products of collisions between fast potassium atoms and nitromethane molecules using a crossed molecular-beam technique. The negative ions formed in such collisions were analysed using time-of-flight mass spectroscopy. The six most dominant product anions are NO2 , O , CH3NO2 ,...

Catalytic conditions for the α-arylation of aryl nitromethanes have been discovered using parallel microscale experimentation, despite two prior reports of the lack of reactivity of these aryl nitromethane precursors. The method efficiently provides a variety of substituted, isolable diaryl nitromethanes. In addition, it is possible to sequentially append two different aryl groups to nitrometha...
