Disperse Dyes from Alkylanthraquinones.II.
Journal of Synthetic Organic Chemistry, Japan, 1965 A series of dispersing dyes containing a β-methyl group and an α-amino group have been synthesized in such a way that those substituents are not located in adjacent positions to each other on the ring structure. The starting compounds employed were the Diels-Alder adducts obtained from 2, 3-dimethylbutadiene with naphthazarine and with 5-nitro-2, 3 ...
