as Raschig rings or placed within the PASSflow TM microreactor affords technical devices that are well suited for performing palladium-catalyzed carbon-carbon cross-coupling reactions in the flow-through mode. Reusability of the immobilized precatalyst as well as applications in the microwave field were investigated. Experiments with thiol- and pyridine-based scavengers were carried out, which revealed
将肟基钯环配位固定到形状为拉西环或放置在 PASSflow TM 微反应器中的聚(乙烯基吡啶)/玻璃复合材料上,提供了非常适合在流动中进行钯催化的碳-碳交叉偶联反应的技术设备-直通模式。研究了固定化预催化剂的可重复使用性以及在微波领域的应用。进行了基于硫醇和吡啶的清除剂的实验,结果表明活性钯物质很可能由性质未知的纳米颗粒组成,并且聚(乙烯基吡啶)载体对这些颗粒具有清除性能。
