    Description / Table of Contents: Abstract On treating the oxime of 1-chloroacetylaminofluoren-9-one (6) with dilute aqueous potassium hydroxide, 3,4-dihydro-2H-fluoreno[1,9-ef]-1,4-diazepin-3-one-1-oxide (7), is formed; heating of 1-aminoacetylaminofluoren-9-one (10) and condensation of 1-aminofluoren-9-one with glycine ester hydrochloride both yield 3,4-dihydro-2H-fluoreno[1,9-ef]-1,4-diazepin-3-one (11). It is shown that both7 and11 are derivatives of fluoreno[1,9-ef]-1,4-diazepine (2) and that7 is the 1-oxide of11. The syntheses of several other derivatives of2 are reported.
    Notes: Zusammenfassung Beim Behandeln von1-Chloracetylaminofluoren-9-on-oxim (6) mit verd. KOH entsteht 3,4-Dihydro-2H-fluoreno[1,9-ef]-1,4-diazepin-3-on-1-oxid (7); durch Erhitzen von 1-Aminoacetyl-amino-fluoren-9-on (10) sowie durch Kondensation von 1-Aminofluoren-9-on mit Glycinesterhydrochlorid wird 3,4-Dihydro-2H-fluoreno[1,9-ef]-1,4-diazepin-3-on (11) erhalten. Es wird bewiesen, daß es sich bei7 und11 um Derivate des Fluoreno[1,9-ef]-1,4-diazepins (2) handelt und daß7 das 1-Oxid von11 ist. Die Synthesen weiterer Derivate von2 werden beschrieben.

    Description / Table of Contents: Abstract 1-Aminofluoren-9-one is brominated and chlorinated in glacial acetic acid and it is shown that the reaction products are 1-amino-4-bromo-, 1-amino-2,4-dibromofluoren-9-one and 1-amino-4-chloro- and 1-amino-2,4-dichlorofluoren-9-one, respectively. Electron densities (net charges) and bond orders of1 are calculated using the simple HMO-method.
    Notes: Zusammenfassung 1-Aminofluoren-9-on (1) wird in Eisessig bromiert bzw. chloriert und es wird gezeigt, daß es sich bei den Reaktionsprodukten um 1-Amino-4-brom- bzw. 1-Amino-4-chlorfluoren-9-on und um 1-Amino-2,4-dibrom- bzw. 1-Amino-2,4-dichlorfluoren-9-on handelt. Elektronendichten (bzw. Nettoladungen) und Bindungsordnungen von1 wurden mittels der einfachen Hückelmethode (HMO) berechnet.
