2-naphthylamines is reported herein. Readily available cyclohexanones and amines (especially alkylamines) are transformed smoothly to target products. Aromatic amines can be achieved from all aliphatic reagents under aerobic metal-free reaction conditions. Control reactions show that the combinational use of elemental sulfur and molecular oxygen is exceptionally essential for this dehydrogenative aromatizaiton
