Reaction of 1-acetylenic derivatives of anthraquinone with hydrazine affording substituted 4H-anthra[9,1-cd]-1,2-diazepin-8-ones and 7H-dibenzo[de,h]quinolin-7-ones is reported.

, p. 1971 - 1974 (1998)
1-Acetylenyl-9,10-anthraquinones react with an excess of NH2NH2 at 80-115°C to give a mixture of substituted 7H-dibenzo[de,h]quinolin-7-ones and anthra[9, 1-cd]-1,2-diazepin-8-ones. The latter compounds undergo reductive contraction
