| | 3-Nitrobenzyl bromide Usage And Synthesis |
| Chemical Properties | Pale Yellow Crystalline Solid | | Uses | 3-Nitrobenzyl bromide was used in the synthesis of 1,4-disubstituted imidazoles. | | Synthesis | General procedure for the synthesis of 3-nitrobenzyl bromide from 3-nitrobenzyl alcohol: Powdered 3-nitrobenzyl alcohol (0.5 mmol) was mixed with halosilanes (0.55 mmol) in a 4 mL screw-capped vial and stirred or heated at room temperature. The reaction mixture was kept at 70-75 °C for 0.5-24 h, during which the reaction progress was monitored by TLC. Upon completion of the reaction, the crude product was cooled to room temperature and the volatile by-product (TMS) was removed by evaporation under reduced pressure (30-35 °C).2O. The residue was confirmed by 1H NMR analysis. If necessary, the pure 3-nitrobenzyl bromide was purified by column chromatography on dry silica to obtain pure 3-nitrobenzyl bromide. Detailed experimental data, including isolated yields, spectral and other characterization data, are given in the Final Product Characterization section of the Supporting Information. | | References | [1] Tetrahedron Letters, 2016, vol. 57, # 22, p. 2430 - 2433
