Cationic palladium(II) catalyst realized facile C-Hactivation of aryl urea with arylboronic acids at roomtemperature. This reaction is extremely mild to carry out aromatic C-Hactivations through electrophilic substitution.

Cationic palladium(II) complexes have been found to be highly reactive towards aromatic C-H activation of arylureas at room temperature. A commercially available catalyst [Pd(MeCN)4](BF4)2 or a nitrile-free cationic palladium(II) complex generated in situ from the reaction of Pd(OAc)2 and HBF4, effectively catalyzes C-H activation/cross-coupling reactions between aryl iodides, arylboronic acids and
