present transformation. The reaction most probably proceeds through the Co(0 or I) complex-promoted generation of a radical (R(•)) followed by addition to C(60). This hydroalkylation method was applied to the synthesis of zinc porphyrin attached C(60) (2l), dendrimer attached C(60) (2m), and fullerene dimer (2n), which were not easily available through the previously known methods.
C(60) 与反应性烷基
溴化物 1 (RBr) 在 Mn 还原剂和 H(2)O 在环境温度下的共催化加氢烷基化得到单烷基化的 C(60) (2) 以良好到高产率。在 Ar 气氛下使用 CoLn/Mn/H(2)O 是目前转型成功的关键。该反应最有可能通过 Co(0 或 I) 配合物促进生成自由基 (R(•)),然后添加到 C(60)。这种加氢烷基化方法适用于合成附有 C(60) (2l) 的
锌卟啉、附有 C(60) (2m) 的树枝状聚合物和
富勒烯二聚体 (2n),这些化合物不容易通过先前已知的方法获得。
