Abstract

In a ligand exchange reaction between BHal3 (Hal = Cl, Br) and the tetraalkylsilanes Et4Si, (Me3Si)2CH2 or Ph2CHSiMe3, the alkylhaloboranes EtBBr2 or MeBHal2 and the alkylhalosilanes Et3SiBr, HalMe2SiCH2SiMe3, (HalMe2Si)2CH2, and Ph2CHSiMe2Br, resp., are formed. Similarly, the methyloligosilanes (Me3Si)2SiMe2 react with BHal3 (Hal = Cl, Br, I) via methyl-halogen-transfer to give HalMe2SiSiMe3 (Hal = Cl, Br, I), (HalMe2Si)2 (Hal = Br, I), HalMe2SiSiMe2SiMe3, (Me3Si)2SiMeHal, HalMe2SiSiMeHalSiMe3, (HalMe2Si)SiMe2 (Hal = Cl, Br) or (BrMe2Si)2SiMeBr besides MeBHal2 (Hal = Cl, Br, I) and Me2BI, resp.
