In reaction of nitroethane lithium salt with sodium nitrite in DMSO, DMF or HMPA involving polyhaloalkanes 1,1-dinitroethane formed in a high yield. The highest yield was obtained with bromo-and iododerivatives. The reaction fits to a kinetic equation of over all second order: the first with respect to the nitroethane anion, and the first in polyhaloalkane. The rate constants of the process are linearly dependent on the electron affinities of the perhaloalkanes molecules.
