A family of N-substituted 3,4-alkylenedioxypyrrole includes monomers for of formula (I) electropolymerization to conjugated polymers and key intermediates for the preparation of the monomers. The preparation of the //-substituted 3,4-alkylenedioxypyrroles is carried out via a synthetic intermediate, an ester substituted dihydroxypyrrole. The synthetic method to prepare the //-substituted 3,4-alkylenedioxypyrrole intermediates and ultimately the N-substituted 3,4-alkylenedioxypyrrole monomers begins with a reaction to form the ester substituted dihydroxypyrrole.
一种N-取代的3,4-烷基二氧杂吡咯家族包括单体的公式(I),用于电聚合成共轭聚合物和制备单体的关键中间体。制备N-取代的3,4-烷基二氧杂吡咯通过合成中间体,即酯取代的二羟基吡咯进行。制备//-取代的3,4-烷基二氧杂吡咯中间体,最终制备N-取代的3,4-烷基二氧杂吡咯单体的合成方法始于反应形成酯取代的二羟基吡咯。
