Pyridine-functionalized MCM-41 catalyzed reactions between tetracyanoethylene and various activated CH-acid compounds are described. These reactions afford the corresponding pyran annulated heterocyclic ring systems in high yields at room temperature within a few minutes. The work-up procedure is very simple and the products do not require further purification. The catalyst can be recycled and reused for several times without observable loss of performance.
描述了吡啶官能化的MCM-41催化四氰基乙烯与各种活性CH-酸化合物之间的反应。这些反应在室温下几分钟内就能以高产率得到相应的吡喃稠合杂环体系。后处理过程非常简单，产物无需进一步纯化。该催化剂可以循环使用多次，而性能没有明显损失。
