Ketone Deprotonation Mediated by Mono- and Heterobimetallic Alkali and Alkaline Earth Metal Amide Bases: Structural Characterization of Potassium, Calcium, and Mixed Potassium−Calcium Enolates

Abstract

Potassium, calcium, and mixed potassium-calcium amide combinations have been shown to be efficient reagents in enolization reactions, and a set of representative intermediate mono- and heterobimetallic enolates have been successfully isolated and crystallographically characterized.
