中文摘要：

一个新奇水溶性的、没有磷化氢的木钉“按” triazole palladacycle 成功地被综合了。作为 precatalyst， palladacycle 与多达 9.8 ×10 ⁵ 的周转数字(吨) 在整洁的水里向 Suzuki-Miyaura 和没有铜的 Sonogashira 跨 coupling 展出了优异催化活动。另外，没有反应的重要损失，催化剂能被再使用至少 3 次。

英文摘要：

A novel water-soluble, phosphine-free PEG ＂click＂ triazole palladacycle has been successfully synthesized. As a precatalyst, the palladacycle exhibited superior catalytic activity towards Suzuki-Miyaura and copper-free Sonogashira cross-coupling in neat water with the turnover numbers （TONs） of up to 9.8 × 10^5. In addition, the cata- lyst could be reused at least 3 times without significant loss of reactivity.
