Structures of Three Lithium Ester Enolates by X-ray Diffraction: Derivation of Reaction Path for Cleavage into Ketene and Alcoholate

Article abstract of DOI:10.1021/ja00305a014

Crystal structure analyses have been carried out for lithium enolates of the following three esters: tert-butyl propionate ((Z)-1), tert-butyl 2-methylpropionate (2), and methyl 3,3-dimethylbutanoate ((Z)-3).Enolates (Z)-1 and 2 are dimeric (with one TMED
