【摘要】 将工业废料一甲基三氯硅烷通过歧化反应转化为用途广且用量大的有机硅单体(二甲基二氯硅烷)是一种较好方法.笔者曾经对该反应的机理做过前期研究.本文用DFT方法对BCl3催化的该歧化反应进行了理论计算,得出了各物质的几何构型参数;对过渡态作了振动分析,并得出了反应的IRC途径曲线.这一切能较好解释BCl3的催化作用.

【Abstract】 Redistribution is a good method to transform industrial waste (trichloromethyl silane) into dichlorodimethyl silane (which is the most widely used monomer of organic silicon). Concerning the mechanism of this reaction. It is did that its preliminary research of before. Theoretical calculation DFT method was used to study the catalysis for BCl3. The geometric parameters of each material were gained. Vibration analyses were studied for each transition state and the curves of IRC pathway were obtained likewise. It is reasonable that all these explain this reaction mechanism.
