“…The formation of compound 10b not 13b is the result of the postulate that at first the amino group with the higher electron density reacts predominantly. [17][18][19][20] The structural assignment of 9b was supported by the following spectral data: in its 13 C NMR spectrum, the characteristic absorption signal of the C=N atoms appeared at d = 153.3, 152.6 ppm. The methyl carbon resonates in the 1 H NMR spectrum of 9b at d = 21.2 ppm.…”

1‐(Dicyanomethylene)acenaphthene‐2‐one (1) reacts with 1,8‐diaminonaphthalene (2) to yield two products, identified as acenaphtho[1,2‐b]naphtho[1,8‐ef][1,4]diazepine (3) and (Z)‐2‐(8‐aminonaphthalen‐1‐ylamino)‐2‐(2‐oxoacenaphthylen‐1(2H)‐ylidene)acetonitrile (4). On the other hand, (2Z,2′Z)‐2,2′‐(hydrazine‐1,2‐diylidene)diacenaphthylen‐1(2H)‐one (6) was obtained during the condensation process of 1 with hydrazine hydrate (5). Reaction of 1 with 3,4‐diaminotoluene (8b) produces 9‐methylacenaphtho[1,2‐b]quinoxaline (9b) and (Z)‐2‐(2‐amino‐5‐methylphenyl‐amino)‐2‐(2‐oxoacenaphthylen‐1(2H)‐ylidene)acetonitrile (10b). However, treatment of 5,6‐diamino‐pyrimidine‐2,4‐diol hemisulphate (11) with 1 affords acenaphtho[1,2‐g]pteridine‐9,11‐diol (12).

(24. VII. 65) Bekanntlich liegt die Carbonylfrequenz in einem gesattigten Funferringketon (Cyclopentanon) hoher als bei einem gesattigten Sechsen-ingketon (Cyclohexanon) Nun sind wir bei unseren Untersuchungen in der Pyromellitsaure-Reihe (Benzimidazol-und Perimidin-Abkommlinge) [8] auf einige stickstoffhaltige, kondensierte 0x0-Ringsysteme gestossen, welche je nach der Ringgrosse eine unterschiedliche C=O-Absorption zeigten. Da nun die weitere Verfolgung dieser Reihe abhangig war von der Interpretation der auftretenden C=O-Frequenzen, haben wir einige zum Teil noch unbekannte Naphtpyrimidine (Perimidine) hergestellt, um deren 1R.-Spektren mit denjenigen unserer neuen Farbstoffe aus dem Gebiete der Imidazole, Perimidine und Chinophtalone zu vergleichen.[Wir wollten hauptsachlich prufen, ob anhand der 1R.-Spektren einfach und schnell die Grosse des ankondensierten Ringsystems bestimmt und ob ferner die Kondensation von cyclischen Anhydriden mit 0-bzw. #eri-standigen Diaminen verfolgt werden konnte.((Benzoylen-benzimidazolo (I) [9] [lo], ((Phtaloperinon-10)) (11) [ll] [12], ctl,8-NaphtoyIen-benzimidazoln (111) [13] [14], ((Naphtaloperinon), (IV) [15] und das un-
