General Description

1,1,2,2-Tetramethyldisilane is a colorless, flammable liquid with a chemical formula of C4H16Si2. It is a type of organosilicon compound and is often used as a precursor in the synthesis of silicon-containing polymers and ceramics. It is also used as a reagent in the production of various silicon-based materials and as a building block in the construction of complex organic molecules. Additionally, 1,1,2,2-Tetramethyldisilane has potential applications in the semiconductor industry as a precursor for silicon deposition and as a protective coating for surfaces. However, it is important to handle this chemical with care as it is highly flammable and can react violently with oxidizing agents.

PROCESS FOR THE PRODUCTION OF ORGANOHYDRIDOCHLOROSILANES

The invention relates to a process for the manufacture of organomonosilanes, in particular, bearing both hydrogen and chlorine substituents at the silicon atom by subjecting a silane substrate comprising one or more organomonosilanes, with the proviso that at least one of these silanes has at least one chlorine substituent at the silicon atom, to the reaction with one or more metal hydrides selected from the group of an alkali metal hydride and an alkaline earth metal hydride in the presence of one or more compounds (C) acting as a redistribution catalyst.

METHOD FOR PRODUCING SILICON HYDRIDE COMPOUND

PROBLEM TO BE SOLVED: To provide a method for producing a silicon hydride compound by converting a silicon-halogen bond to a silicon-hydrogen bond with a boron hydride, wherein the method allows the reaction to proceed quickly and can be applied to a variety of substrates. SOLUTION: A method for producing a silicon hydride compound includes the step of converting a silicon-halogen bond to a silicon-hydrogen bond with a boron hydride, in the presence of an organic solvent containing nitrogen.
