The present work reports dendronized polymer based catalysis in which the dendritic cavity and surface functional groups are the reactive centers due to the formation of dendritic unimolecular micelle in aqueous medium. First generation amine functionalized tris(hydroxymethyl)propane initiated polyepichlorohydrin cored dendronized polymer (TMP-PECH-Amine-G1) was synthesized and was properly characterized with different analysis techniques. High functional group capacity, thermal stability and good water solubility are the eye-catching features of the TMP-PECH-Amine-G1 catalyst. The catalytic activity of TMP-PECH-Amine-G1 was studied by synthesizing 4-aryl-1H-1,2,3-triazoles by one pot condensation reaction of aromatic aldehydes, nitromethane and sodium azide. The synthesized catalyst offered high yield of products with low catalyst loading in green reaction media without the presence of any external additives. The catalyst was regenerated for six cycles of reaction without substantial loss in activity. This is the first reported method where homogeneous amine functionalized dendronized polymer was used as an organo catalyst for the synthesis of 4-substituted triazoles.

本工作报道了基于树枝状聚合物的催化，其中由于在水性介质中形成树枝状单分子胶束，因此树枝状空腔和表面官能团是反应中心。合成了第一代胺官能化的三（羟甲基）丙烷引发的聚表氯醇核化的树突化聚合物（TMP-PECH-胺-G1），并用不同的分析技术对其进行了适当表征。高官能团容量，热稳定性和良好的水溶性是TMP-PECH-胺-G1催化剂的醒目的特征。通过合成4-芳基-1 H研究了TMP-PECH-胺-G1的催化活性。-1,2,3-三唑通过芳族醛，硝基甲烷和叠氮化钠的一锅缩合反应。合成的催化剂可在绿色反应介质中以高催化剂负载量提供高收率的产品，而无需任何外部添加剂。催化剂再生了六个反应周期，而活性没有实质损失。这是首次报道的方法，其中均相胺官能化的树枝状聚合物被用作有机催化剂来合成4-取代的三唑。
