Palladium-catalyzed cross-dehydrogenative coupling of uracil or caffeine with unactivated arenes has been developed. The approach was characterized by using atmospheric pressure of molecular oxygen as the sole oxidant. Functional groups such as halo, ester, nitro, nitrile and ether are well-tolerated under the reaction conditions. This novel strategy provides a straightforward, facile and economical route to C6-aryl uracil derivatives or C8-aryl caffeine derivatives.
