Anthraquinone dyes. Part VI. Nuclear alkylation of 1-aminoanthraquinone leuco-derivative
Abstract
2-Alkyl derivatives are obtained by the action of acetaldehyde and propionaldehyde on the 1-aminoanthraquinone vat. The analogous reactions involving benzaldehyde, furfural, cinnamaldehyde, and glyoxal, and the possibility of nuclear methylation of the substituted 1-aminoanthraquinones were studied.
