 Title    Metallacycloalkane, III [1] Darstellung und Charakterisierung von a.a'-Dipyridyl-Nickelacyclopentan Preparation and Characterisation of a,a'-Bipyridyl-nickelacyclopentane  
 Abstract    The title compound was synthesised from bis-l,5-cyclooctadienenickel, a,a'-bipyridyl and 1,4-dibromobutane in 83% yield and its structure determined by X-ray diffraction (a = 16.600, b = 10.837, c = 14.815 Ä; ß = 153.05°; C2/c, Z = 4; symmetry: C2 with square planar coordinated nickel; Ni-C: 1.949 A). a,a'-Bipyridylnickelcyclopentane reacts with maleic anhydride or methylacrylate under reductive elimination to give cyclobutane in 75 and 57% yield; considerable amounts of butenes are formed, in addition to cyclobutane, upon reaction with borontrifluoride-dibutylether or on thermolysis.
