The BaeyerâDrewsen indigo synthesis (1882) is an organic reaction in which indigo is prepared from 2-nitrobenzaldehyde and acetone [1] [2] The reaction was developed by von Baeyer and Viggo Drewsen [ da] in 1880 to produce the first synthetic indigo at laboratory scale. This procedure is not used at industrial scale. [3]
The reaction is classified as an aldol condensation. As a practical route to indigo, this method was displaced by routes from aniline. [4]
In the English literature this reaction is sometimes called BaeyerâDrewson reaction, although the author of the original paper was spelled Drewsen.
