Pd-catalyzed regioselectiveC–H activation method that is used for C–H deuteration, carbonylation, halogenation, and oxidation of arene substrates substituted by two N-heterocycles. When conducted in acetic acid (AcOH), these reactions occur at the five-membered palladacycle sites, whereas they switch to the six-membered palladacycle sites in trifluoroacetic acid (TFA). This controllable regioselective C–H
