The development of a rational protocol to realize the complete regioselectivity and the capability to switch regioselectivity is an appealing yet challenging task. Herein, a regiodivergent C−H arylation of 2-pyridylthiophenes has been demonstrated via the choice of RuII and PdII catalysts. The reactions proceeded smoothly in a good regioselective manner to afford the corresponding C3- and C5-arylated
