Nitriles used to be known as cyanides; the smallest organic nitrile is ethanenitrile, CH3CN, (old name: methyl cyanide or acetonitrile – and sometimes now called ethanonitrile). 31643-49-9, formula is C8H3N3O2, Name is 4-Nitrophthalonitrile. Nitriles are found in many useful compounds, including methyl cyanoacrylate, used in super glue, and nitrile rubber, a nitrile-containing polymer used in latex-free laboratory and medical gloves. Name: 4-Nitrophthalonitrile.
Li, Siqi;Huang, Zhipeng;Liu, Huifang;Liu, Meijiang;Zhang, Chaofeng;Wang, Feng research published 《 Polar hydrogen species mediated nitroarenes selective reduction to anilines over an [FeMo]Sx catalyst》, the research content is summarized as follows. An efficient approach for the chemoselective synthesis of arylamines RNH2 (R = 2-fluorophenyl, 2-acetyl-4,5-dimethoxyphenyl, 2-pyridyl, etc.) from nitroarenes RNO2 and hydrazine over an iron-molybdenum sulfide catalyst ([FeMo]Sx) is presented. The heterogeneous hydrogen transfer reduction can be efficiently carried out at 30°C and provides anilines with 95-99% selectivities. The in situ gas product anal. demonstrates that [FeMo]Sx can catalyze the decomposition of N2H4 to H* species, not H2. Combining with the kinetic anal. of the aniline generation rates from nitrobenzene and intermediates, the nitro group reduction to the nitroso group is confirmed to be the rate-determining step. The pos. slope of Hammett’s equation suggests that the critical intermediate in the rate-determining step is in the neg. state, which suggests that the active H* should be in polar states (Hδ- and Hδ+). These findings will provide a novel route for the synthesis of substituted anilines and broaden the application of MoSx catalysts under mild conditions.
Name: 4-Nitrophthalonitrile, 4-Nitrophthalonitrile, also known as 4-Nitrophthalonitrile, is a useful research compound. Its molecular formula is C8H3N3O2 and its molecular weight is 173.13 g/mol. The purity is usually > 95%.
4-Nitrophthalonitrile is a chemical substance that can be synthesized by the reaction of sodium carbonate with 3,4,5-trimethoxybenzyl alcohol. It can also be prepared using nitro phenol and sodium hydroxide. 4-Nitrophthalonitrile has been shown to have high photochemical activity in the presence of light. The frequency shift of its infrared spectrum is indicative of a nucleophilic addition reaction mechanism. 4-Nitrophthalonitrile has been used as an intermediate for producing other chemicals, such as herbicides and pharmaceuticals., 31643-49-9.
