摘要: 甲硅硫醇兼有有机硅和有机硫化物的特点。本文对它的脱氢反应途径进行微观动力学解析,并与甲硫醇的脱氢反应引进行了比较,结果表明它们的反应途径相似。活化能对甲硅硫醇的脱氢反应有利,而活化熵和频率因子则对甲硫醇的脱氢反应有利。

Abstract: The reaction ergodography was performed for the dehydrogenation pathway of silylthiol, and the comparing study was made for this result with that of the dehydrogenation of methanethiol. It reveals both of these two reaction pathways to be concerted, but nonsynchronous. The activation energy is favour to the dehydrogenation of silylthiol, however, the activation entropy and frequency factor are favour to the dehydrogenation of methanethiol.

Key words: Ab initio, Dehydrogenation pathway, Silylthiol
