A cross-dehydrogenative coupling (CDC) reaction between tertiary amines and nitroalkanes has been realized under an oxygen atmosphere in water simply by using graphene-supported RuO₂ as the catalyst, which was made from water-soluble graphene with sulfonic groups and RuCl₃·nH₂O to form RuO₂·nH₂O nanocomposites in situ. In contrast to RuCl₃·nH₂O and RuO₂·nH₂O, the graphene-supported RuO₂ nanoparticles exhibited higher activity and stability for the aerobic CDC reaction in water.
