The following Arrhenius parameters for the forward and reverse steps of trichlorosilyl radical additions to trans-but-2-ene, cis-but-2-ene, cis-pent-2-ene, 2-methyl-but-2-ene and cyclopentene have been obtained by a competitive method. The relevant elementary reactions are ·SiCl3+ CH3COCH3→(CH3)2ĊOSiCl3(3), ·SiCl3+CC⇌Ċ—[graphic omitted]—SiCl3(5, –5), and —[graphic omitted]—SiCl3+ HSiCl3→ H[graphic
以下Arrhenius参数用于将三氯甲硅烷基自由基加至反式-丁-2-烯,顺式-丁-2-烯,顺式-戊-2-烯,2-甲基-丁-2-烯和环戊烯的正向和反向步骤已经通过竞争方法获得。相关的基本反应是·的SiCl 3 + CH 3 COCH 3 →(CH 3)2 ĊOSiCl 3(3),·的SiCl 3 + C ^ C ^ ⇌ C- [图形省略] -SiCl 3(5,-5),和- [省略图] -SiCl 3 + HSiCl 3 →H [省略图]-[省略图] SiCl3 +·SiCl 3(6),[省略图示]。
