In water it's better: In‐situ‐generated [Ru(O2CR)2(arene)] catalysts efficiently perform the direct ortho‐arylation of functional arenes with chloroarenes or chloroheterocycles in water (see scheme; KOPiv=potassium pivalate), without the need for a surfactant. The activity of these catalysts is higher in water than in organic solvents.
在
水中则更好:原位生成的[Ru(O 2 CR)2(
芳烃)]催化剂可有效地将功能
芳烃与
水中的
氯芳烃或
氯杂环化合物进行直接邻位芳构化(请参阅方案; KOPiv =新
戊酸钾),而无需需要表面活性剂。这些催化剂在
水中的活性高于在有机溶剂中的活性。
