Summary:The pyrolysis of alkyldichloroboranes such as MeBCl 2BCHCHBCl 2, Cl 2BCH 2BCl 2 or (Cl 2B) 3CH at 450°C leads to the formation of hexachloro-hexaboraadamantane, C 4H 4B 6Cl 6 (I). The structure - determined by X-ray diffraction - and the spectroscopic data of 2,4,6,8,9,10-hexachloro-2,4,6,8,9,10-hexaboraadamantane are in agreement with the classical description as an organoborane, rather than as a molecule with a carborane framework. Substitution reactions are described. The bromo compound C 4B 4B 6Br 6 can be prepared by heating Me 2BBr or MeBBr 2 to 520°C. Bei der Pyrolyse von Alkyldichlorboranen wie MeBCl 2, Cl 2BCHCHBCl 2, Cl 2BCH 2BCl 2 oder (Cl 2B) 3CH bei 450° C entsteht Hexachlor-hexaboradamantan, C 4H 4B 6Cl 6 (I). Die durch Röntgenbeugung ermittelte Struktur und die spektroskopischen Daten von 2,4,6,8,9,10-Hexachlor-2,4,6,8,9,10-hexaboradamantan weisen sie als klassisches Organoboranmolekül aus, nicht als eines mit Carborangerüst. Substitutionsreaktionen werden beschrieben. Die Bromverbindung C 4H 4B 6Br 6 kann durch Erhitzen von Me 2BBr oder MeBBr 2 auf 520°C hergestellt werden.
