several fundamental carbon-carbon bond-forming reactions. The catalyst is recovered quantitatively by simple filtration and reused several times without loss of catalytic activity, and no Sc leaching was observed in all reactions (<0.1 ppm). In addition, several solvents are available, and these aspects are suitable for high-throughput organic synthesis (HTOS). To the best of our knowledge, this is the
已经开发了一种用于 Sc(OTf)3 的新型固定技术,即聚合物胶束嵌入 (PMI) 方法。PMI Sc(OTf)3 在几个基本的碳-碳键形成反应中非常活跃。催化剂通过简单过滤定量回收并重复使用数次而不会损失催化活性,并且在所有反应中均未观察到 Sc 浸出(<0.1 ppm)。此外,还有几种溶剂可用,这些方面都适用于高通量有机合成(HTOS)。据我们所知,这是第一个利用聚合物胶束固定路易斯酸的例子。
