Usage

General Description

1,2-Dibromotetramethyldisilane, tech-95 is a chemical compound primarily used as a reagent in organic synthesis and as a building block in the production of various silicon-based materials. It is a clear, colorless liquid with a strong, unpleasant odor and is classified as a hazardous substance. 1,2-DIBROMOTETRAMETHYLDISILANE, tech-95 is commonly used in the manufacturing of polymers, adhesives, and sealants, as well as in the synthesis of specialty chemicals. It is important to handle 1,2-dibromotetramethyldisilane with care, as it is flammable and may cause irritation to the skin, eyes, and respiratory system upon exposure.

Preparation of oligosilanes containing perhalogenated silyl groups (-SiX3, -SiX2-, >SiX-, X = Cl, Br) and their hydrogenation by stannanes

Starting from methylphenylsubstituted oligosilanes the disilanes SiX3-SiXi,Me3-i (i = 0, 1, 2; X = Cl, Br), trisilanes SiX2(SiXiMe3-i) (i = 0, 1) and branched tetrasilanes SiX(SiXMe2)3 were synthesized and their behavior towards the Lewis-base catalyzed hydrogenation by stannanes was investigated. In the case of methylchlorodisilanes SiCl3-SiCliMe3-i Si-Si bond cleavage competes with the hydrogenation reaction.

Ligand Exchange Reactions between Haloboranes and Alkylsilanes

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, HalMe2Si-CH2-SiMe3, (HalMe2Si)2CH2, and Ph2CHSiMe2Br, respectively, are formed.Similarly, the methyloligosilanes (Me3Si)2 (1) and (Me3Si)2SiMe2 (2) react with BHal3 (Hal = Cl, Br, I) via methyl-halogen-transfer to give HalMe2Si-SiMe3 (Hal = Cl, Br, I), (HalMe2Si)2 (Hal = Br, I), HalMe2Si-SiMe2-SiMe3, (Me3Si)2SiMeHal, HalMe2Si-SiMeHal-SiMe3, (HalMe2Si)SiMe2 (Hal = Cl, Br) or (BrMe2Si)2SiMeBr besides MeBHal2 (Hal = Cl, Br, I) and Me2BI, respectively.
