IN an earlier paper1 discussing the ZnCl2-HCl-catalysed polycondensation of N,N-dimethylaminomethyl-ferrocene I to give polymer II, the formation of intermediates III and IV was postulated on the basis of the stoichiometry of the starting materials required and the composition of by-product V (C10H9Fe = ferrocenyl). While III could indeed be isolated, no interception of IV was possible.
在早先一篇讨论 ZnCl2-HCl 催化 N,N-二
甲基氨基甲基二茂铁 I 缩聚生成聚合物 II 的论文1 中,根据所需起始材料的
化学计量学和副产物 V(C10H9Fe =
二茂铁基)的组成,推测会形成中间体 III 和 IV。虽然 III 确实可以分离出来,但 IV 却无法截取。
