An environmentally friendly method for the synthesis of a series of novel, unsymmetrical Michlers ketone analogues, [4-(dialkylamino)phenyl](aryl) methanones, via nucleophilic aromatic substitution of (fluorophenyl)(aryl) methanones with various amines in water- is described. The reaction products are formed in high yields and additional purification is not required. The aqueous solvent and unreacted amines can be recycled. Georg Thieme Verlag Stuttgart · New York.
