A site-selective direct arylation reaction of carbazole and other N-heterocycles with diazo-naphthalen-2(1H)-ones has been developed. While Au(I)-NHC catalysts lead to selective C3-arylation, palladium acetate allows for selective N-H arylation, displaying...

Pd(ii)-catalyzed direct arylation of chromones and enaminones gives divergent site-selectivities. Computational and experimental studies reveal a switch in mechanism, from a C3-selective CMD mechanism to a C2-selective carbopalladation pathway. This model accounts for the opposite selectivities of enaminone and chromone, and also correctly predicts selectivities for the C–H functionalization of heteroaromatic substrates as a function of the coupling partner.
