Ceric(Ⅳ)-mediated Oxidative Addition of 1,3-Dicarbonyl Compounds to MCPs:A Facile Access to Dihydrofuran Derivatives Incorporating Cyclopropyl Groups

Alkylidenecyclopropanes undergo ceric（Ⅳ） ammonium nitrate （CAN）-mediated addition reaction with 1,3-dicarbonyl compounds leading to dihydrofuran derivatives incorporating cyclopropyl groups in moderate yields.

四价铈离子引发丙烯酰胺在玉米淀粉上接枝共聚合的研究

本文研究了在Ce^(4+)氧化还原体系引发下,丙烯酰胺在玉米淀粉上的接枝共聚反应。发现玉米淀粉经过酸性处理后容易与丙烯酰胺接枝共聚。探讨了反应温度、丙酰烯胺与玉米淀粉的配比、四价铈离子浓度、加料方式对接枝共聚的影响。
