Reaction medium containing water-surfactant mixture

The present invention is directed to reaction mixtures comprising a water-surfactant mixture and a co-solvent. This technology reduced the amount of organic solvents needed for performing chemical reactions. Furthermore, compared to reaction mixtures lacking the co-solvent, solvation of the reactants and products of the chemical reaction is greatly enhanced, leading to a significantly improved yield, purity, reproducibility and robustness.
