microscopies, inductively coupled plasma and thermogravimetric techniques. The catalyst shows high activity in the Suzuki, Heck and Stille cross‐coupling reactions and the synthesis of 5‐substituted 1H‐tetrazoles from sodium azide (NaN3). These methods have the advantages of high yields, green reaction conditions, simple methodology and easy separation and workup. Copyright © 2016 John Wiley & Sons, Ltd.
通过将钯固定在有机改性的介孔二氧化硅的表面上,已经合成了一种环保的非均相催化剂。使用X射线衍射,傅立叶变换红外和能量色散X射线光谱,透射和扫描电子显微镜,电感耦合等离子体和热重分析技术对制得的催化剂进行了表征。该催化剂在Suzuki,Heck和Stille的交叉偶联反应中以及由叠氮化钠(NaN 3)合成5取代的1 H-四唑类中显示出高活性。这些方法具有高收率,绿色反应条件,简单的方法以及易于分离和后处理的优点。版权所有©2016 John Wiley&Sons,Ltd.
