compound introduction

聚合物键合的4-（二甲基氨基）吡啶是DMAP的聚合物键合当量。聚合物键合的4-（二甲氨基）吡啶已被用作酰化反应的催化剂。该化合物是2％交联的。 应用： 聚合物结合的4-（二甲氨基）吡啶在Michael加成和亚硝酸消除工艺步骤中用作负载碱，该步骤涉及在通用和基于方案的有效连续流动下使用β-硝基丙烯酸酯作为起始物料合成噻吩-2-羧酸酯。在固体非均相催化下，它还可以作为负载型催化剂，以环状2-硝基酮为起始原料制备ω-硝基酯。 4-(Dimethylamino)pyridine, polymer-bound is a polymer-bound equivalent of DMAP. 4-(Dimethylamino)pyridine, polymer-bound has been used as a catalyst for acylation reactions. The compound is 2% crosslinked.
