General description

Nitromethane is an aliphatic nitro compound that is commonly used as a solvent for chemical processing and analysis.

Application

Nitromethane can be used as a solvent in the:
  • FeCl3-catalyzed Friedel-Crafts alkylation of indoles with alcohols.
  • Cobalt-catalyzed dehydration of aldoximes to nitriles.
  • Chemoselective oxidation of alcohols to carbonyl compounds.
  • Gold-catalyzed hydroarylation of aryl-substituted alkynes.

Nitrogenous disinfection byproducts (N-DBPs) such as haloacetonitriles (HANs) and halonitromethanes (HNMs) are formed during water chlorination. Preozonation is sometimes applied to control trihalomethane (THM) formation, but this may risk promoting the formation of HNMs and HANs. The role of ozone
