An effective CuI-trans-N,N'-dimethylcyclohexane-1,2-diamine (DMCDA)-K2CO3-cataIyzed coupling reaction of 2-pyridones with aryl halides is described. Under our conditions, DMCDA was found to be an effective catalyst that facilitates the coupling reactions even in toluene, a common industrial solvent. In addition, 3-bromopyridine could also be coupled effectively under these conditions, indicating that the catalytic reactivity of this system is high. The reaction could be applied for polymer modification and iterative oligo-pyridone synthesis. (c) 2005 Elsevier Ltd. All rights reserved.

Palladium-catalyzed weak chelation-assisted oxidative cross-dehydrogenativecoupling of arenes has been accomplished. The use of medicinally important pyridones as the intrinsic directing group, regioselectivity, 2-fold C–H activation, and late-stage modification of bioactive compounds are the important practical features.
