Chemistry:4-Nitrobenzaldehyde
From HandWiki
4-Nitrobenzaldehyde is an organic compound with the formula O
2NC
6H
4CHO. It is one of three isomers of nitrobenzaldehyde. It contains a nitro group para-substituted to an aldehyde.
4-Nitrobenzaldehyde is obtained by oxidation of 4-nitrotoluene or hydrolysis of 4-nitrobenzalbromide:[1]
- O
2NC
6H
4CHBr
2 + H
2O → O
2NC
6H
4CHO + 2 HBr
In the laboratory, the oxidation is achieved with chromium(VI) oxide in acetic anhydride, which affords nitrobenzyldiacetate.[2]
