Nitroaldol (“Henry”) reactions between nitroalkanes and aldehydes in the presence of a catalyst and a two-phase reaction medium produce nitroalcohols at increased reaction rates compared to single-phase organic solvent systems, and do not require use of surfactants as is typical of single-phase aqueous solvent systems and solventless systems. The reaction medium comprises an organic solvent phase and an aqueous solvent phase. The aqueous solvent may be 100% water.
