若干快速自由基重排反应的动力学及其机理研究

With the generous support of this project by NSFC, we carried out the investigation of the application of fast radical rearrangement in metal carbene C-H bond insertion mechanism, we also discovered new reaction of a-diazo carbonyl compounds involving radical intermediate. In addition, we studied the new reaction of metal carbene and the reaction mechanism of metal carbene.

快速自由基重排反应的动力学研究引起了人们的极大兴趣。我们将应用竞争反应的方法测量若干含氧或氮三元环碳自由基的快速开环重排反应的速率，并通过研究该类重排反应的电子效应了解其反应机理。此外，还将应用快速自由基重排反应做为机理探针研究金属卡宾分子内碳氢键插入反应的机理。
