The pyrolysis of alkyldichloroboranes such as MeBCl2, Cl2BCH=CHBCl2, Cl2BCH2BCl2 or (Cl2B)3CH at 450 deg C leads to the formation of hexachloro-hexaboraadamantane, C4H4B6Cl6 (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-hexaboradamantane 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 C4H4B6Br6 can be prepared by heating Me2BBr or MeBBr2 to 520 deg C.
