Methods and recent development of isolation of structurally characterizable alkali, alkaline earth and lanthanide metal ketyl radical complexes were reviewed in the paper. 介绍了利用金属离子的配位作用捕获并分离重要有机反应中间体&自由基中间体的研究方法和最新进展。
Capture and detection of ketyl radical 自由基的捕获与检测
When the amine was used as a triplet quencher, the ketyl radical of ketocoumarin can be observed evidently. 当以胺类化合物为猝灭剂时,可以清楚地观察到半片呐醇自由基的生成,并得到了它的瞬态吸收光谱。
