Abstract
AbstractA 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.
