Highly efficient ferrocene functionalized Schiff base containing copper(ii) complex enables diverse 1,2,3-triazoles under green condition with parts-per-million catalyst level.

In the present study, a new photoactive bimetallic Cu-Au@g-C 3 N 4 catalytic system was designed by impregnating Cu and Au NPs over the graphitic carbon nitrite (g-C 3 N 4 ) surface. Characterization of the catalyst using multiple techniques illustrated that very small-sized Cu and Au NPs were monodispersed on the g-C 3 N 4 surface, which were obtained by the in situ reduction of the metal salts using sodium borohydride. The as-synthesized bimetallic Cu-Au@g-C 3 N 4 catalyst efficiently catalyzed the hydroxylation of benzene (HOB) via C-H activation [a]
