Meta-substituent effects on benzyl free-radical stability was written by Fisher, Thomas H.;Dershem, Stephen M.;Prewitt, M. Lynn. And the article was included in Journal of Organic Chemistry in 1990.COA of Formula: C7H7BrN2O2 This article mentions the following:
A series of 5-substituted 3-cyanotoluenes was synthesized, and the relative rates of N-bromosuccinimide bromination were determined in benzene at 80 鎺矯. The resulting 锜?sub>F閳?/sup> values for meta Me, H, Br, NO2, and CN were found to be 0.03, 0.00, -0.03, -0.04, and -0.10, resp. Of these meta substituents, all but Me were found to be destabilizing to the intermediate benzyl free radical. These meta substituent results are consistent with reported 锜?sub>浼?/sub>閳?/sup> and 锜?sub>c閳?/sup> values and cast doubt upon reports that assume meta substituents have no influence on free-radical stability. In the experiment, the researchers used many compounds, for example, 2-Bromo-4-methyl-6-nitroaniline (cas: 827-24-7COA of Formula: C7H7BrN2O2).
2-Bromo-4-methyl-6-nitroaniline (cas: 827-24-7) belongs to organobromine compounds. Organo bromine compounds are versatile compounds and are widely used in diverse fields. Organo bromine derivatives are used in the dye sector, as an indicator in analytical chemistry (Bromothymol blue is a popular indicator). When the molecular ion is detected, the bromine and chlorine isotope patterns are very distinct, but caution is to be exercised for certain mixed chlorinated/brominated compounds, which can look similar to homohalogen patterns.COA of Formula: C7H7BrN2O2
