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·nH 2O to form RuO2·nH2O nanocomposites in situ. In contrast to RuCl3·nH2O and RuO 2·nH2O, the graphene-supported RuO2 nanoparticles exhibited higher activity and stability for the aerobic CDC reaction in water.

Iminium ions generated in situ via copper(I) bromide catalyzed oxidation of N-aryl amines readily undergo [4 + 2] cycloadditions with a range of dienophiles. This method involves the functionalization of both a C(sp 3)-H and a C(sp2)-H bond and enables the rapid construction of polycyclic amines under relatively mild conditions.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Quality Control of 2-Phenyl-1,2,3,4-tetrahydroisoquinoline, you can also check out more blogs about3340-78-1
