Abstract
A possible tridentate complex between Grignard reagents and bis[2-(N,N-dimethylamino)ethyl] ether moderates the reactivity of the Grignard reagents and enables the selective reaction with acid chlorides to provide aryl ketones in high yield without a subsequent second nucleophilic addition.
