that constructed by zirconium cations and terephthalate with high chemical and thermal stability. Using pristine UiO‐66 nanocrystals as the catalysts, the carbon–carbon bond formation based on denitrogenative substitution of aryl diazonium salts has been achieved under mild condition. The C–H arylation of both enol acetates and heteroarenes could be performed in aqueous medium without other metal assistance
