Challenging Suzuki–Miyaura cross couplings associated with novel crop protection active ingredients from Corteva Agriscience, Arylex and Rinskor, can be performed in water using parts per million (ppm) levels of a Pd catalyst. Each coupling required a distinct set of reaction conditions to achieve maximum selectivities and chemical yields. By way of comparison, this chemistry is not only performed
具有挑战性的Suzuki-Miyaura交叉偶联与来自Corteva Agriscience,Arylex和Rinskor的新型作物保护活性成分有关,可以在水中使用百万分之几(ppm)的Pd催化剂进行。每个偶联都需要一组独特的反应条件,以实现最大的选择性和化学收率。相比之下,这种化学反应不仅在对环境负责的水性胶束条件下进行,而且还涉及降低濒临灭绝的钯的负载量(3-5倍),从而实现了更具可持续性的流程。
