## Abstract The tetrameric cubic structure established for lithium enolates in the solid state is used as a model to discuss several facets of enolate chemistry: solubility, effects of cosolvents, addition to aldehyde and acid chloride, influence of mixed aggregates on diastereo‐ and enantioselecti

✦ Synopsis
Abstract
The structures of the crystalline lithium enolates derived from 3, 3‐dimethyl‐2‐butanone and from cyclopentanone have been determined by X‐ray analysis. Both structures are tetrameric aggregates based on a Li~4~O~4~‐cube, each Li^+^‐ion being additionally bonded to the O‐atom of a tetrahydrofuran solvent molecule.
