Two is better than one! A combination of two ligands (Phen.H2O and PPh3) with Pd catalyst offers a highly efficient catalytic system for the direct C−H arylation of benzothiazole and benzoxazole with aryl halides. Mechanistic studies including kinetic isotope effect experiments and computational investigations suggests that two ligands may work cooperatively to enhance the catalytic activity in the
