Lianyungang Klinechem Co.,Ltd | Updated: Nov 29, 2018

The Baeyer–Drewson indigo synthesis (1882) is an organic reaction in which indigo is prepared from 2-nitrobenzaldehyde and acetone [1][2]

The reaction is classified as an aldol condensation. As a practical route to indigo, this method was displaced by routes from aniline.[3]

Mechanism

Note

In the English literature this reaction is usually called Baeyer–Drewson reaction, although the author of the original paper was called Drewsen.
