A CONVENIENT SYNTHESIS OF (TRICHLOROMETHYL)CHLOROSILANES

In the presence of a catalytic amount of triphenylphosphine, 1,1,2,2-tetrachloro-1,2-dimethyldisilane reacted smoothly under mild conditions with carbon tetrachloride to produce (trichloromethyl)-methyldichlorosilane (1) in good yield. (Trichloromethyl)dimethyl-chlorosilane was also readily prepared by the triphenylphosphine-promoted transfer of the trichloromethyl group from (1) to dimethyldichlorosilane.

Synthetic Pathways to Simple Di- and Trisilylmethanes: Potential Starting Materials for the CVD Deposition of Amorphous Silicon a-SiC:H

Methods for the preparation of simple silaalkanes with a high content of silicon and hydrogen have been explored.Target molecules, like H3SiCH2SiH3 and HC(SiH3)3, may serve as precursor molecules for the production of photovoltaic elements through thermal or discharge (plasma) CVD processes.Among a variety of synthetic pathways, the reactions between HSiCl3 and HCCl3 in the presence of an amine (Benkeser reaction) and the direct synthesis from silicon and polychloromethanes proved most promising for large scale preparations.The CH2X2/KSiH3 metathesis is most useful on the laboratory scale. - The Grignard synthesis was employed for partly methylated homologues, like H3SiCH2SiH2CH3, H3SiCH2SiH(CH3)2, H3SiCH2Si(CH3)3, and related molecules.The magnesium reduction of CHBr3/SiCl4 and CHBr3/CH3SiCl3 mixtures serves best for the preparation of HC(SiCl3)3, which can be converted into HC(SiH3)3 using LiAlH4.Attempts to synthesize tetrasilylmethane via the same route, C(SiH3)4, led only to the formation of HC(SiH3)3. - Key words: Amorphous Silicon a-SiC:H, Disilylmethane, Trisilylmethane, Direct Synthesis, Polysilylmethanes

CONVERSION OF DISILANES TO FUNCTIONAL MONOSILANES XIV. REACTIONS OF METHYLCHLORODISILANES WITH gem-POLYHALIDES CATALYZED BY ORGANIC BASES

The reaction of methylchlorodisilanes with gem-polyhalides in the presence of organic bases has been investigated.The compounds CXCl2SiMeCl2 (X = Cl, H, F and SiMeCl2) were obtained in moderate to high yields from Cl2MeSiSiMeCl2 and polyhalomethanes (e.g., CCl4, CHCl3, CFCl3 and CCl3SiMeCl2) with PPh3 or Bu4NCl as catalyst.The reaction of 1,1,2-trichlorotrimethyldisilane with CCl4 afforded a 1:1 mixture of CCl3SiMeCl2 and CCl3SiMe2Cl.Also, XC6H4CCl2SiMeCl2 (X = H and 4-Cl) were obtained in moderate yields from Cl2MeSiSiMeCl2 and XC6H4CCl3 with Bu4NCl or Bu4NF as catalyst.
