An efficient and selective Pd(0)-catalyzed sp3 CâH bond arylationâoxidation of 4-methylquinazolines is reported. The method enables the introduction of arylketone at the benzylic position of 4-methylquinazolines without the use of an additional directing group, and atmospheric oxygen is used as the sole oxidant.
