3-Methyl-4-nitroanisole (cas: 5367-32-8) belongs to ethers. Ethers are good solvents partly because they are not very reactive. Most ethers can be cleaved, however, by hydrobromic acid (HBr) to give alkyl bromides or by hydroiodic acid (HI) to give alkyl iodides. At room temperature, ethers are pleasant-smelling colourless liquids. Relative to alcohols, ethers are generally less dense, are less soluble in water, and have lower boiling points. They are relatively unreactive, and as a result they are useful as solvents for fats, oils, waxes, perfumes, resins, dyes, gums, and hydrocarbons. Vapours of certain ethers are used as insecticides, miticides, and fumigants for soil.Computed Properties of C8H9NO3

Rhodium-catalysed ortho-alkynylation of nitroarenes was written by Tan, Eric;Montesinos-Magraner, Marc;Garcia-Morales, Cristina;Mayans, Joan Guillem;Echavarren, Antonio M.. And the article was included in Chemical Science in 2021.Computed Properties of C8H9NO3 This article mentions the following:

The ortho-alkynation of nitro-(hetero)arenes RNO2 (R = pheynl, 3-fluorophenyl, 2-bromothiophen-5-yl, etc.) takes place in the presence of a Rh(III) catalyst to deliver a wide variety of alkynylated nitroarenes, e.g., I regioselectively. These interesting products could be further derivatized by selective reduction of the nitro group or palladium-catalyzed couplings. Exptl. and computational mechanistic studies demonstrate that the reaction proceeds via a turnover-limiting electrophilic C-H metalation ortho to the strongly electron-withdrawing nitro group. In the experiment, the researchers used many compounds, for example, 3-Methyl-4-nitroanisole (cas: 5367-32-8Computed Properties of C8H9NO3).

Amoros, I. et al. published their research in Water Science and Technology in 2000 | CAS: 5367-32-8

3-Methyl-4-nitroanisole (cas: 5367-32-8) belongs to ethers. Ether is less polar than esters, alcohols or amines because of the oxygen atom that is unable to participate in hydrogen bonding due to the presence of bulky alkyl groups on both sides of the oxygen atom. But ether is more polar than alkenes. Electron-deficient reagents are also stabilized by ethers. For example, borane (BH3) is a useful reagent for making alcohols. Pure borane exists as its dimer, diborane (B2H6), a toxic gas that is inconvenient and hazardous to use. Borane forms stable complexes with ethers, however, and it is often supplied and used as its liquid complex with tetrahydrofuran (THF).Synthetic Route of C8H9NO3

An assessment of the toxicity of some pesticides and their metabolites affecting a natural aquatic environment using the Microtox system was written by Amoros, I.;Connon, R.;Garelick, H.;Alonso, J. L.;Carrasco, J. M.. And the article was included in Water Science and Technology in 2000.Synthetic Route of C8H9NO3 This article mentions the following:

The conservation and preservation of aquatic ecosystems is of utmost importance due to the high diversity and d. of species and their complex food network. The evaluation of the potential adverse environmental impact caused by pesticides entering water bodies is an important parameter in aquatic toxicity. The toxicity of the insecticide, fenitrothion and two of its metabolites, 3-methyl-4-nitrophenol and 3-methyl-4-nitroanisole, and of the herbicides thiobencarb and molinate, commonly used in rice fields in Valencia near the protected area of lake Albufera, was tested by the Microtox system. The 15 min EC50 values obtained with the marine luminescent bacterium Vibrio fischeri showed that the thiobencarb was the most toxic of the 3 tested pesticides with an EC50 value of 0.03 mg/L. The EC50 values of the first 2 steps of the fenitrothion hydrolysis indicated that while the first metabolite, 3-methyl-4-nitrophenol, was as toxic as its parent compound, a decreased toxicity was observed for the second metabolite, 3-methyl-4-nitroanisole. To analyze the toxic effects of pesticides in complex mixtures the EC50 values of fenitrothion, molinate, and thiobencarb as pure substances and their mixtures were compared. The impact of the pesticides in the natural ecosystem was also studied and a protective effect of lake water was observed In the experiment, the researchers used many compounds, for example, 3-Methyl-4-nitroanisole (cas: 5367-32-8Synthetic Route of C8H9NO3).

Suzuki, Hideharu et al. published their research in Synlett in 2000 | CAS: 5367-32-8

3-Methyl-4-nitroanisole (cas: 5367-32-8) belongs to ethers. Of all the functional groups, ethers are the least reactive ones. Ether bonds are quite stable towards bases, oxidizing agents and reducing agents. Autoxidation is the spontaneous oxidation of a compound in air. In the presence of oxygen, ethers slowly autoxidize to form hydroperoxides and dialkyl peroxides. If concentrated or heated, these peroxides may explode. To prevent such explosions, ethers should be obtained in small quantities, kept in tightly sealed containers, and used promptly.Quality Control of 3-Methyl-4-nitroanisole

The Reissert indole synthesis was found to unexpectedly give 3-hydroxy-1,2,3,4-tetrahydro-2-quinolone derivatives I (R = H, 6-MeO, 5-MeO, 3-CO2Et, 3-Me, 3-MeO, 3-Me2CHO), sometimes in a high ratio to the expected Et indole-2-carboxylate derivatives, depending on the conditions of the catalytic reduction of the intermediate (2-nitrophenyl)pyruvates. This reactivity is characteristic in the preparation of 7-substituted indoles. In the experiment, the researchers used many compounds, for example, 3-Methyl-4-nitroanisole (cas: 5367-32-8Quality Control of 3-Methyl-4-nitroanisole).

Disilanes as oxygen scavengers and surrogates of hydrosilanes suitable for selective reduction of nitroarenes, phosphine oxides and other valuable substrates was written by Gevorgyan, Ashot;Mkrtchyan, Satenik;Grigoryan, Tatevik;Iaroshenko, Viktor O..

In this report, the reaction of nitroarenes RNO2 (R = Pr, cyclohexyl, 2-methylphenyl, pyridin-3-yl, etc.) with hexamethyldisilane under various conditions affords a different range of compounds with excellent selectivity. In particular, the reaction of nitroarenes with hexamethyldisilane using a CsF/TBAB/toluene system provides suitable azo compounds, while in the presence of a CsF/TBAB/[Pd]/EtOH system this hexamethyldisilane acts as a novel surrogate of gaseous trimethylsilane, thus, reducing nitroarenes to corresponding anilines RNH2. The synthetic value of the developed methodol. was further extended by the reduction of a wide range of substrates including N-oxides such as 2-methyl-quinoline-1-oxide, isoquinoline-2-oxide, 2,6-dimethylpyridine-1-oxide, 2-phenylpyridine-1-oxide, sulfoxides such as methanesulfinylbenzene, (benzenesulfinyl)benzene, 1-methanesulfinyl-4-methylbenzene, [(phenylmethane)sulfinylmethyl]benzene, phosphine oxides such as [[(diphenylphosphoroso)methyl](phenyl)phosphoryl]benzene, [[3-(diphenylphosphoroso)propyl](phenyl)phosphoryl]benzene, (diphenylphosphoryl)benzene, etc. In the experiment, the researchers used many compounds, for example, 3-Methyl-4-nitroanisole (cas: 5367-32-8Computed Properties of C8H9NO3).
