Homogeneous PdII-catalyzed oxidative C-H arylations have the potential to streamline the synthesis of pharmaceuticals, agrochemicals, and other complex organic molecules by bypassing the pre-oxidation of substrates to aryl halides for use in traditional cross-coupling. Existing methods, however, commonly exhibit poor catalyst performance despite high Pd loading (e.g., 10 mol%) and require (super)stoichiometric quantities of undesirable oxidants, such as benzoquinone and silver(I) salts. Understanding the mechanistic basis for poor catalyst efficacy will greatly enhance their utility. Large-scale application of these reactions demands robust catalyst systems with low catalyst loading and use of inexpensive and environmentally sustainable oxidants (e.g., O2). This thesis focuses on understanding and developing selective aerobic C-H arylations that exhibit high catalyst turnovers.
