Abstract
A stable tert-butyl(10-phenyl-9-anthryl)nitroxide (BPAN) radical was newly synthesized and used for the capture/characterization of reactive radicals. Adducts obtained from the reactions of BPAN with in situ generated reactive radicals showed excellent stability, assuring complete isolation and purification. The structures of the adducts were established by LC-MS and NMR analyses.
摘要
新合成了一种稳定的叔丁基（10-苯基-9-蒽基）氮氧自由基（BPAN），并将其用于活性自由基的捕获/表征。BPAN 与原位生成的活性自由基反应得到的加合物具有极好的稳定性，确保了完全的分离和纯化。通过 LC-MS 和 NMR 分析确定了加合物的结构。
