Abstract
A process for making nitroalkanes in which an alpha-bromoalkanoic acid is reacted with an alkali metal nitrite, e.g. NaNO.sub.2, in the presence of the magnesium ion (Mg.sup.++) in an aprotic solvent to form a chelate. Neutralization of the chelate with a mineral acid produces a nitroalkane having one less carbon atom than the reactant bromoalkanoic acid.
