DETAILS

Description (English)
Packaging
5, 25 g in glass bottle
Features and Benefits
This support amine has been developed to serve as a Knoevenagel catalyst. Because it is polymer-bound, it eliminates piperidine-derived by-products and reduces transesterification while using alcohol as a solvent. Recently, this resin was shown to be recyclable in the synthesis of benzopyrones using "resin capture" methodology.

Features and Benefits
这种载体胺已被开发用作 Knoevenagel 催化剂。因其为聚合物键合型胺,因此在用醇作溶剂时,可避免哌啶衍生副产物并减少转酯反应。最近证实,此树脂可在采用"树脂捕获"方法合成苯并吡喃酮中循环利用。
