Isopropyl-alkylamines 2 react with 2,3-dichloro-1,4-naphthoquinone (1) to give red 2-chloro-3-isopropyl-alkylamino-1,4-naphthoquinones 3 and with 2,3-dichloro-1,4-naphthoquinone/acetaldehyde to give blue 2-chloro-3-isopropylalkylamino-vinyl-1,4-naphthoquinones 7. It is evident that the formation of 7 is preferred sterically to the formation of 3. The reaction between 2, 1
