3-硝基-4-溴苯腈 - Reference Information
| Use | 4-bromo-3-nitrobenzonitrile is an important intermediate in organic synthesis, because of its aromatic ring with two second class substituents Nitro and cyano, at the same time there is a bromine can participate in the reaction and the two compounds have a wide range of applications in the field of organic synthesis. |
| preparation | with iodine/ammonia system L121 as oxidant, the high yield of 4-bromobenzonitrile was obtained by ammoxidation of 4-bromobenzaldehyde. The reaction time was short, the reaction conditions were mild and the yield was high. The corresponding nitration product was obtained by nitration of 4-bromobenzonitrile. Due to the positioning of the aromatic ring on the cyano group, the use of low temperature conditions can achieve the aromatic ring of the single nitrification. The synthesis reaction formula is as follows: |
