Descripción

General description

Nitroethane reacts with sodium to afford sodium-nitroethane. Solution of nitroethane in caustic potash reacts with bromine to afford monobromnitroethane. It can undergo nitroaldol (Henry) condensation reaction with various aldehydes in the presence of copper(II) arylhydrazone complexes (catalyst).[1]
pK of nitroethane is 8.60.4
Nitroethane is an aprotic solvent with high polarity[2], which on oxidation with glucose oxidase gives nitrite, acetaldehyde and hydrogen peroxide as the major products.[3]

Application

Nitroethane may be used in the synthesis of the following compounds:

• β-nitro amine derivatives[4]
• β-aryl nitroethylenes[5]
• 2-alkylthio-3-alkylamino-1-aryl(hetaryl)-4-nitropentene[6]

Other Notes

major impurity is 2-nitropropane
