 Title    Übergangsmetallkomplexe von Diazenen, XVI [1] Struktur und Mößbauerdaten von (2.3-Diazanorbornen)Fe3(CO)9 Transition Metal Complexes of Diazenes, XVI [1] Structure and Mössbauer Data of (2,3-Diazanorbornene)Fe3(CO)g  
 Abstract    The molecular structure of (2,3-diazanorbornene)Fe3(CO)9 consists of a triangular Fe3(CO)g group bound to the diazene unit. The seven-coordinated Fe(CO)3 group forms two Fe-N bonds with lengths of 1.974 and 1.965 Ä, each of the two six-coordinated Fe(CO)3 groups has slightly shorter Fe-N-bonds of 1.898 and 1.903 Ä. One Fe-Fe distance, 2.612Ä, is longer than the two other ones, 2.572 and 2.582 A, which are in the range of typical single bonds. The presence of seven-and six-coordinated iron carbonyl groups is also demonstrated by the Mössbauer spectrum showing signals with quadrupole splittings of 1.23 and 0.78, 0.62 ± 0.01 mm/s, respectively.

 Title    Perfluorbenzyl-Stickstoff-Derivate Perfluorobenzyl Nitrogen Derivatives  
 Abstract    In the HgF2-assisted addition of Cl2 and Br2 to C6F5CN the compounds C6F5CF=NX (3, 5: X = Cl, Br) and C6F5CF2NX2 (2, 4: X = Cl, Br) are formed. Photochemical decomposition of the dibromoamine (4) gives the diazene C6F5CF2-N=N -CF2C6F5 (6) in 31% yield. The struc­ ture of 6 has been determined by X-ray diffraction.

 Title    Iron Carbonyl Assisted Synthesis of l,2-Diazepin-3-ones from Cyclic Diazenes and Alkynes [1]  
 Abstract    , 2a, c are prepared by an iron carbonyl mediated reaction sequence from alkynes and cyclic 1,2-diazenes. The latter are first converted into hexacarbonyl diiron complexes which react with two molecules of an alkyne to afford tricyclic carbonyl iron compounds I —III. Oxidative degradation with bromine leads to these novel heterocycles whose structure is confirmed by an X-ray analysis of lb.
