Abstract The reaction of aryloxymethyl epoxide with anilines under solvent‐free conditions and microwave irradiation affords high yields of 1‐arylamino‐3‐aryloxypropan‐2‐ols. The reaction was rapid and completely regioselective.

Iron hydroxide-Fe(OH)(3) and iron oxides (Fe3O4 and Fe2O3) were successfully prepared and characterized. These materials were employed as efficient and environmentally benign heterogeneous catalysts for the epoxide ring opening reaction of various alyloxy, terminal and meso epoxides with aromatic and aliphatic amines under solvent free condition at room temperature. Out of these, nano-sized Fe(OH)(3) (IH-1) showed better catalytic activity to give the product beta-amino alcohols in excellent yield (up to similar to 96%) and high regioselectivity in 10-360 min. The catalyst was successfully recycled and reused eight times with no loss in catalytic activity. (C) 2013 Published by Elsevier B.V.
