“…With the same catalytic system, aniline could also be N-mono-methylated and N-di-methylated. Based on previous studies, the same group [86] synthesized a 3D-type ZIF-7 complex in catalysis of the same N-functionalization of amines in 2021 (Scheme 71). The aniline was selected as model substrate and converted into various products, such as MPC (main), MMPC, MA, and DMA.…”

N‐alkyl anilines are a series of common and versatile compounds which not only have been used as reaction solvents, acid‐accepters, and organic‐bases, but also in synthesis of dyes, pharmaceuticals, and anti‐colodal. The N‐methyl and/or N,N‐dimethyl anilines are the most representative ones among these. Due to their widespread uses, numerous works have been reported on synthetic strategies in the past decades. The studies on N−H methylations of anilines mainly focus on selection of reagents, selection of catalysts, or ligands design. Different transition‐metals, e. g., Ir, Ru, Pd, and et. al, with different ligands have been used in the methylation protocols. Methanol (CH3OH), carbon dioxide (CO2), formaldehyde (HCHO), or dimethyl carbonate ((CH3)2CO3) was used as C source, and hydrogen (H2) or silanes as H source. In this work, we would like to summarize the latest advances on the synthesis of N‐methyl (N,N‐dimethyl included) anilines and derivatives. This review provides an overview of reactants and catalyst, as well as an emphasis on the scope of substrates and proposed reaction mechanism for each work.

Isocyanate, a pivotal chemical intermediate to synthesize polyurethane with widespread applications in household appliances, automobiles, and construction, is predominantly produced via the phosgene process, which currently holds a paramount status in industrial isocyanate production. Nonetheless, concerns arise from the toxicity of phosgene and the corrosiveness of hydrogen chloride, posing safety hazards. The synthesis of isocyanate using nonphosgene methods represents a promising avenue for future development. This article primarily focuses on the nonphosgene approach, which involves the formation of carbamate through the reaction of nitro-amino compounds with carbon monoxide, dimethyl carbonate, and urea, among other reagents, subsequently leading to the thermal decomposition of carbamate to get isocyanate. This paper emphasizes the progress in catalyst development during the carbamate decomposition process. Single-component metal catalysts, particularly zinc, exhibit advantages such as high activity, cost-effectiveness, and compatibility with a wide range of substrates. Composite catalysts enhance isocyanate yield by introducing a second component to adjust the active metal composition. The central research direction aims to optimize catalyst adaptation to reaction conditions, including temperature, pressure, time, and solvent, to achieve high raw material conversion and product yield.
