本文对甲硅烷基胺1a和1b与O-1（2）在乙腈和乙腈-甲醇（80：20）中的反应进行了动力学和产物研究。已经获得表明激基复合物（1）形成之后的电子转移步骤的指示。然而，自由基阳离子的命运取决于溶剂。自由基阳离子在MeCN-MeOH中经历脱甲硅烷基化并在MeCN中经历脱质子化。
A kinetic and product study has been carried out for the reactions of silylamines 1a and 1b with O-1(2) in MeCN and (80:20) MeCN-MeOH. Indications suggesting an electron-transfer step following exciplex (1) formation have been obtained. However, the fate of the radical cation is solvent dependent. The radical cation undergoes desilylation in MeCN-MeOH and deprotonation in MeCN.
