The reactions of 2-SiH3B5H8 and μ-SiH3B5H8 with BCl3 and BBr3 produce 2-(ClSiH2)B5H8, μ-(ClSiH2)B5H8, and 2-(BrSiH2)-B5H8, in high yield. The 2-(ClSiH2)B5H8 and 2-(BrSiH2)B5H8 can also be prepared from the aluminum halide catalyzed reactions of 2-SiH3B5H8 with HCl and HBr, respectively. In all cases, halogenation occurs exclusively at the silicon atom. The new compounds have been characterized by elemental analyses and infrared, 11B nmr, 1H nmr, and mass spectral data. Deuterium exchange between DCl and 2-SiH3B5H8 or 2-(ClSiH2)B5H8, catalyzed by aluminum chloride, occurs at the apical, B(1), terminal position.
