Ruthenium-catalyzed meta-C–H bond alkylation of aryl 2-pyridyl ketones†
Abstract
The first example of meta-selective CAr–H bond functionalization of aryl 2-pyridyl ketones has been developed using [Ru(p-cymene)Cl2]2 as the catalyst and alkyl bromide as the coupling reagent. This development provides an efficient strategy for modifying the meta-position of aryl 2-pyridyl ketone skeletons, which are found in various functional molecules.
