Uses

2-Nitromesitylene is a substituted nitrobenzene derivative used in medicine and functional healthy food, pharmaceutical compounds comprising substituted nitrobenzene derivatives for prevention and?/or treatment of various diseases.

Purification Methods

Crystallise it from EtOH, or a small volume of MeOH and cool in an ice-salt bath (m 43.5o). [Powell & Johnson Org Synth Coll Vol II 449 1943, Beilstein 5 H 410, 5 III 923, 5 IV 1028.]

Check Digit Verification of cas no

The CAS Registry Mumber 603-71-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,0 and 3 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 603-71:
(5*6)+(4*0)+(3*3)+(2*7)+(1*1)=54
54 % 10 = 4
So 603-71-4 is a valid CAS Registry Number.

The Inhibiting Effects of Tetraalkylammonium Cations on Simple Heterogeneous Electron Transfer Reactions in Polar Aprotic Solvents

Fawcett, W. Ronald,Fedurco, Milan,Opallo, Marcin

, p. 9959 - 9964 (1992)

Kinetic data for the electroreduction of nitromesitylene at mercury in propylene carbonate have been determined in the presence of tetraalkylammonium salts of varying chain length, both as a function of electrode potential and temperature.Although the standard rate constant decreases with increase in cation size, the experimental activation enthalpy is independent of the cation for variation in this ion from tetraethylammonium to tetraoctylammonium.These results indicate that the tetraalkylammonium ions are adsorbed on the electrode forming a blocking layer whose thickness increases with alkyl chain length.Electron transfer to the redox center takes place by tunneling through this film.Theoretical estimates of the activation enthalpy support this conclusion and suggest that the redox reaction occurs in a region where solvent reorganization determines the largest portion of its magnitude.

Selective Mild Oxidation of Anilines into Nitroarenes by Catalytic Activation of Mesoporous Frameworks Linked with Gold-Loaded Mn3O4 Nanoparticles

Armatas, Gerasimos S.,Daikopoulou, Vassiliki,Koutsouroubi, Eirini D.,Lykakis, Ioannis N.,Skliri, Euaggelia

, (2021/11/01)

This work reports the synthesis and catalytic application of mesoporous Au-loaded Mn3O4 nanoparticle assemblies (MNAs) with different Au contents, i. e., 0.2, 0.5 and 1 wt %, towards the selective oxidation of anilines into the corresponding nitroarenes. Among common oxidants, as well as several supported gold nanoparticle platforms, Au/Mn3O4 MNAs containing 0.5 wt % Au with an average particle size of 3–4 nm show the best catalytic performance in the presence of tert-butyl hydroperoxide (TBHP) as a mild oxidant. In all cases, the corresponding nitroarenes were isolated in high to excellent yields (85–97 %) and selectivity (>98 %) from acetonitrile or greener solvents, such as ethyl acetate, after simple flash chromatography purification. The 0.5 % Au/Mn3O4 catalyst can be isolated and reused four times without a significant loss of its activity and can be applied successfully to a lab-scale reaction of p-toluidine (1 mmol) leading to the p-nitrotulene in 83 % yield. The presence of AuNPs on the Mn3O4 surface enhances the catalytic activity for the formation of the desired nitroarene. A reasonable mechanism was proposed including the plausible formation of two intermediates, the corresponding N-aryl hydroxylamine and the nitrosoarene.

HNO3/HFIP: A Nitrating System for Arenes with Direct Observation of π-Complex Intermediates

Lu, Le,Liu, Huixin,Hua, Ruimao

supporting information, p. 3197 - 3201 (2018/06/11)

This report describes an efficient nitrating system for the nitration of arenes at room temperature by using an equivalent of nitric acid in HFIP (1,1,1,3,3,3-hexafluoroisopropanol). The π-complex intermediate of an arene with a nitronium ion stabilized by HFIP can be directly observed by UV-vis spectra and is supported by theoretical calculations.
