通过使用草酰胺或 4-羟基吡啶甲酰胺作为配体,Cu 催化的(杂)芳基卤化物磺酰胺化反应具有出色的反应范围。对于溴化物,仅需要 2–5 mol% CuI 和草酰胺。对于氯化物,需要将催化负载增加到 10 mol% Cu 2 O 和配体。在此条件下实现了四种含氯市售药物的直接磺酰胺化和两种磺胺类药物的制备。

Provided herein are methods and compositions for selective and targeted cancer therapy, in particular certain benzothiophenes, benzothiazoles, oxalamides, N-acyl ureas and chromones, and their use in selectively treating certain adenocarcinomas. In some embodiments, the selective toxicity of the compounds may be mediated through SCD1 and/or CYP450 such as CYP4F11.
The widespread crisis of plastic pollution demands discovery of new and sustainable approaches to degrade robust plastics such as nylons. Using a green and sustainable approach based on hydrogenation, in the presence of a ruthenium pincer catalyst at 150 °C and 70 bar H2, we report here the first example of hydrogenative depolymerization of conventional, widely used nylons and polyamides, in general
塑料污染的普遍危机要求发现新的和可持续的方法来降解尼龙等坚固的塑料。使用基于氢化的绿色和可持续方法,在 150 °C 和 70 bar H2 的钌钳催化剂的存在下,我们在这里报告了常规、广泛使用的尼龙和聚酰胺的氢化解聚的第一个例子。在相同的催化条件下,我们还演示了聚氨酯加氢生成二醇、二胺和甲醇。此外,我们还展示了一个例子,其中从氢化过程中获得的单体(和低聚物)可以脱氢回到分子量大致相似的聚(低聚)酰胺,从而完成聚酰胺回收的闭环循环。基于实验和密度泛函理论研究,我们提出了由金属-配体协同促进的过程的催化循环。总体而言,这种前所未有的转变,尽管是在概念验证层面,为更清洁的尼龙回收途径提供了一种新方法。
