Recently I am researching about CHEMOSELECTIVE HYDROGENATION; 1 ATM; REDUCTION; CATALYST; NITROBENZENE; PERFORMANCE; ANILINE; BONDS; H-2, Saw an article supported by the National Natural Science Foundation of ChinaNational Natural Science Foundation of China (NSFC) [21868011]; National Key R&D Program of China [2017YFC1103800]. Product Details of 100-19-6. Published in ROYAL SOC CHEMISTRY in CAMBRIDGE ,Authors: Sun, ST; Du, MY; Zhao, RX; Jv, XC; Hu, P; Zhang, Q; Wang, B. The CAS is 100-19-6. Through research, I have a further understanding and discovery of 1-(4-Nitrophenyl)ethanone
The hydrogenation of nitroarenes is one of the most important strategies for the preparation of anilines. However, it is still a great challenge to develop mild and efficient synthetic routes toward aniline synthesis, particularly those employing both non-precious metal catalysts and low-pressure H-2. Herein, we report a highly efficient protocol for the selective hydrogenation of nitroarenes in neutral H2O using H-2(1 atm) over a heterogeneous Zn(0) catalyst under mild conditions. The nitro groups of an array of nitroarenes can be converted into -NH(2)with up to 99% conversions and a selectivity of >99%, even when functionalized with easily reducible substituents, or in the presence of aromatic ketones or styrene. This study might open an avenue for the selective hydrogenation of nitroarenes over a zinc catalyst using 1 atm H-2.
