Palladium-catalyzed ligand directed C–H activation/halogenation reactions have been extensively explored. Both the nature of the directing group and the substitution pattern on the arene ring of the substrate lead to different reactivity profiles, and often different and complementary products, in the presence and absence of the catalyst.
钯催化的配体定向的C–H活化/卤化反应已得到广泛研究。在存在和不存在催化剂的情况下,导向基团的性质和底物的芳环上的取代图案均导致不同的反应性分布,并且常常导致不同的和互补的产物。
