Abstract

Al–K heterometallic terpene oximate derivatives with uncommon structural features are reported. These species react with an aryl ketone leading to heterometallic enolates via an unusual route. Isolation of a remarkable heterometallic Al–K enolate confirms the cooperative mechanism proposed by DFT calculations, where the oximate ligand has a prominent role. From these enolates the formation of new C–C bonds is straightforward.
