Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>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 9.8×10⁵. In addition, the catalyst could be reused at least 3 times without significant loss of reactivity.</p> </abstract>
