Rhodium­(III)-catalyzed C–H bond functionalization for the synthesis of β-aryl aldehydes and ketones from (hetero)­aryl oximes, pyri­(mi)­dine, as well as pyrazoles and α,β-unsaturated carbonyl compounds has been developed under exceedingly mild reaction conditions. Thus, the versatile rhodium­(III) catalysis features high step- and atom-economy, oxidant-free reaction conditions, and broad substrate scope.
