The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: 3-Bromo-4-chloronitrobenzene( cas:16588-26-4 ) is researched.HPLC of Formula: 16588-26-4.Sheng, Yao; Wang, Xueguang; Xing, Zhikang; Chen, Xiubin; Zou, Xiujing; Lu, Xionggang published the article 《Highly Active and Chemoselective Reduction of Halogenated Nitroarenes Catalyzed by Ordered Mesoporous Carbon Supported Platinum Nanoparticles》 about this compound( cas:16588-26-4 ) in ACS Sustainable Chemistry & Engineering. Keywords: reduction halogenated nitroarene catalyzed carbon platinum nanoparticle. Let’s learn more about this compound (cas:16588-26-4).
Highly dispersed Pt nanoparticles (∼2.2 nm) on ordered mesoporous carbon (Pt/CMK-3-HQ) were first prepared through a two-step impregnation route with aqueous solutions of 8-hydroxyquinoline (8-HQ) and H2PtCl6, resp. The Pt/CMK-3-HQ quant. converted various halogenated nitroarenes to the corresponding haloanilines using hydrazine hydrate with unprecedented activities (e.g., turnover frequency for o-chloronitrobenzene was 30.2 s-1) and exhibited high stability with 20 cycles without decrease in catalytic efficiency. The high activity and chemoselectivity of Pt/CMK-3-HQ were attributed to the cooperation effect between Pt and N species, promoting cleavage of hydrazine to generate more Pt-H- and N-H+ species for reduction of nitro groups and weakening the interaction between halogen groups and Pt atoms for activation of C-halogen bonds.
From this literature《Highly Active and Chemoselective Reduction of Halogenated Nitroarenes Catalyzed by Ordered Mesoporous Carbon Supported Platinum Nanoparticles》,we know some information about this compound(16588-26-4)HPLC of Formula: 16588-26-4, but this is not all information, there are many literatures related to this compound(16588-26-4).
