Both poly(3,4-ethylenedioxythiophene) and poly(pyrrole) mediate a pinacol rearrangement of 1,2-diols. The yields of ketone or aldehyde products are comparable to those observed for treatment with mineral acids or Lewis acids. The advantage of this protocol is a two-phase reaction medium in hydrocarbon solvents that allows facile recovery of the products by simple filtration of the polymer and removal
聚(3,4-乙撑二氧噻吩)和聚(吡咯)均介导1,2-二醇的频哪醇重排。酮或醛产物的产率与用无机酸或路易斯酸处理所观察到的产率相当。该方案的优点是在烃类溶剂中形成两相反应介质,可通过简单过滤聚合物和除去溶剂来轻松回收产物。聚合物和烃溶剂均可被回收并用于随后的反应中。 频哪醇-二醇-PEDOT-聚吡咯-重排
