Abstract

Bisadduct isomers of a H(2)@C(60) derivative with nitroxide addends have been synthesized, isolated and characterized. The (1)H NMRs of endohedral H(2) of the major isomers show well-separated chemical shifts, which could be useful for structural assignment and identification of the purity of the C(60) bisadduct isomers.

摘要

已合成、分离和表征了具有氮氧自由基加合物的 H(2)@C(60)衍生物的双加成异构体。主要异构体的内笼 H(2)的 (1)H NMR 显示出化学位移的良好分离，这对于结构分配和 C(60)双加成异构体的纯度鉴定可能很有用。
