Abstract: Crystal structure analyses have been carried out for lithium enolates of the following three esters: tert-butyl propionate ((Z)-1), tert-butyl2-methylpropionate (2), and methyl 3, 3-dimethylbutanoate ((Z)-3). Enolates (Z)-1 and 2 are dimeric (with one TMEDA per Li atom), whereas (2)-3 is tetrameric (with one THF per Li atom). The Z configuration of 1 and 3 established by X-ray analysis is in agreement with that assigned by Ireland. From a ...
