Synthesis and properties of some 2-nitrobenzylamine derivatives was written by Celnik, Krzysztof;Jankowski, Zdzislaw. And the article was included in Polish Journal of Chemistry in 1978.Category: ethers-buliding-blocks This article mentions the following:
2,E-(O2N)RC6H3CH2NH2.HCl (I, n-R = H, 4-MeO, 5-MeO, 4-Cl, 5-Cl, 4-NO2, 5-NO2) were prepared (48.2-73.2% yield) by treating the corresponding benzyl bromides with hexamethylenetetramine and hydrolyzing the resultant quaternary salts. The ionization constants were determined and found to have a linear relationship to σn constants In the experiment, the researchers used many compounds, for example, 3-Methyl-4-nitroanisole (cas: 5367-32-8Category: ethers-buliding-blocks).
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. The unique properties of ethers (i.e., that they are strongly polar, with nonbonding electron pairs but no hydroxyl group) enhance the formation and use of many reagents. For example, Grignard reagents cannot form unless an ether is present to share its lone pair of electrons with the magnesium atom. Complexation of the magnesium atom stabilizes the Grignard reagent and helps to keep it in solution.Category: ethers-buliding-blocks
