  Abstract:  The direct addition of substituted aromatic amines to 1,3-cyclohexadiene was efficiently catalyzed in a liquid - liquid two phase system comprised of a polar catalyst of Zn(CF3SO3)2 in water and the substrate and reactant mixture in n-heptane. The successful replacement of 1-ethyl-3-methyl-imidazolium trifluoromethanesulfonate with water, a greener and cheaper polar solvent than any ionic liquid (IL), for hydroamination reactions of cyclohexadiene with aromatic amines, was demonstrated.
