Aryldiazonium salts is a novel electrophile.It shows greater reactivity than aryl halides and tolerance to various reaction conditions,which make them potential substitutes for aryl halides and allow the reaction to proceed smoothly under mild conditions.Li etal.reported a novel palladium(Ⅱ) carboxymethylcellulose(CMC-PdⅡ) for Heck-Matsuda reactions of aryldiazonium tetrafluoroborate with olefins,and Suzuki-Miyaura couplings of aryldiazonium tetrafluoroborate with arylboronic acid.Both reactions proceeded at room temperature in water or aqueous ethanol media without the presence of any ligand or base,to provide the corresponding cross-coupling products in good to excellent yields under atmospheric conditions.
