Recent Advances on Heteroatom‐Doped Porous Carbon/Metal Materials: Fascinating Heterogeneous Catalysts for Organic Transformations

“…A simple one‐pot pyrolysis strategy was also applied by Wang and coworkers to produce superfine Ru particles dispersed in the N‐doped carbon (Ru/CN) using melamine, glucose, and ruthenium trichloride as starting materials (Figure 44). [7a] A broad set of halogenated nitroarenes selectively reduced to corresponding haloanilines in the presence of Ru/CN as a heterogeneous catalyst (Scheme 72). The interaction between Ru and N was the main factor affecting the catalytic activity because it could promote the production of hydrogen in an electron‐rich state.…”

Catalyst-Controlled Regioselective Chlorination of Phenols and Anilines through a Lewis Basic Selenoether Catalyst

“…1 H NMR (400 MHz, CDCl 3 ) δ 7.14 (d, J = 8.0 Hz, 1H), 6.96 (d, J = 8.0 Hz, 1H), 6.63 (dd, J = 7.9, 2.5 Hz, 1H), 4.01 (bs, 2H), 2.20 (s, 3H). 13 52 2-Chloro-6-isopropylaniline (22b). 22b was prepared according to the general procedure on a 1 mmol scale and obtained in a 66% yield, as a dark brown oil.…”

Tuning the Electron Density of Metal Nickel via Interfacial Electron Transfer in Ni/MCM-41 for Efficient and Selective Catalytic Hydrogenation of Halogenated Nitroarenes

“…8 Therefore, the scientific and industrial communities have paid extensive research to the efficient conversion of halogenated nitrobenzene into halogenated aniline with high selectivity. 9−13 A series of heterogeneous catalysts based on noble metal Ru, 14 Pd, 6 and Pt 15 were developed in the liquid-phase hydrogenation of halogenated nitrobenzene and exhibited excellent catalytic performance. Unfortunately, the high cost and poor selectivity limited their large-scale application.…”
