The development of various methodologies for the formation of carbon‐nitrogen bonds is one of the valuable tasks in the field of organic synthesis because the final products are extensively utilized in pharmaceuticals, biologically active compounds, and natural products. The utilization of nanosized metal catalysts with high surface energy, large surface‐to‐volume ratio, excellent thermal stability, and reactive morphology in C‐N cross‐coupling reactions has received considerable attention, in recent years. The excellent catalytic performance, the high yield of products, carrying out the reactions under relatively mild and ligand‐free conditions, and less toxicity to the environment, recoverability, and reusability of catalysts for several times without a remarkable degradation in activity are advantages of these nanocatalysts. This review intends to summarize the latest progress in the fabrication of nanocatalysts and their applications in the construction of carbon‐nitrogen bonds via cross‐coupling reactions. Abundant nanocatalysts based on metal and metal oxide nanoparticles/complexes including copper, palladium, nickel, cobalt, silver, gold, zirconium, and zinc have successfully been applied in these reactions. Various aspects of the reactions, different strategies of fabrication of nanocatalysts, and their recyclability have been surveyed. Literature has been investigated from 2015 to 2021.

A nickel(II)-catalyzed oxygen transfer reaction of dibenzylideneacetone-derived N-vinyl-α,β-unsaturated nitrones has been identified for the preparation of polysubstituted 2-(pyridin-2-yl)ethanols in good yields with high atom economy. The scope of the method is described, and mechanistic experiments are discussed. The reaction was easily performed at gram scales, and pyrido[2,3-c]carbazole was obtained in moderate yield over three steps.

We describe the difunctionalization of arylboronic acids to prepare various N-(2-hydroxyaryl)pyridin-2-ones in good yields using N-hydroxypyridin-2-ones as the oxygen and nitrogen sources through a copper(II)-catalyzed Chan−Lam reaction and subsequent BF 3 -promoted selective 1,3-rearrangement of N−O bond in a one-pot procedure. Mechanistic studies reveal that the 1,3-rearrangement selectivity is controlled by the formation of the key aryloxypyridinium salt. The obtained products are easily converted to various useful pyridin-2-one scaffolds.
