Abstract
The reaction of leucoquinizarin with ethylenediamine and N-alkylethylenediamines gives two series of products, 1,4-bisalkylaminoanthraquinones and 6-alkylamino-1,2,3,4-tetrahydronaphtho[2,3-f]quinoxaline-7,12-diones. Higher alkylenediamines give only the 1,4-bisalkylaminoanthraquinones. Analogous reactions with 5,8-dihydrleucoquinizarin are also described.Keywords
