Process for the preparation of p-tert.-butyl benzaldehyde and the derivatives thereof substituted in the nucleus by halogen. |
| abstract |
p-tert.Butylbenzaldehyde and the derivatives thereof which are halogen-substituted at the nucleus are prepared by bromination of p-tert.butyltoluene and the derivatives thereof which are correspondingly halogen-substituted at the nucleus under side-chain halogenation conditions until the benzal bromide is obtained which is then saponified. Practically no undesired bromination at the nucleus or the tert.butyl group takes place. The products obtained are valuable intermediates for the manufacture of pharmaceutical agents, plant protecting agents and dyestuffs. |
