Synthesis of varied N-heterocycles and C–N bond forming reactions catalyzed by novel proficient heterogeneous
Cu–based solid catalysts namely, CuI-zeolites, CuII-HT, and CuII-PMOs are addressed in this review
article. The above-mentioned catalysts have been proved to be remarkable heterogeneous catalysts for many
organic transformations mostly, one-pot MCRs including synthesis of 1,2,3-triazoles through 1,3-dipolar
cycloaddition and 2H-indazoles over heterocyclization of C-N and N-N bond formations and range of C-N bond
forming reactions. These novel synthetic methods offered many advantages including shorter reaction times,
simple reaction procedures, catalyst recyclability, good to moderate yields, and broader substrate scope. All the
aspects related to these approaches are addressed in this comprehensive review.
Keywords: Heterogeneous catalysts, MCRs, Cu-based solid catalysts, N-heterocycles, C–N bond formation, 1, 2, 3-triazoles, 2H-indazoles.
