Few ester enolate crystal structures have been described. The lack of structural information is no doubt due to the fact that the ester enolates undergo a-elimination reactions at or below room temperature. A good discussion of the temperatures at which lithium ester enolates undergo this elimination is presented in the same paper with the crystal structures of the lithium enolates derived from r-butyl propionate (163), r-butyl isobutyrate (164) and methyl 3,3-dimethylbutanoate (165). It is significant Aat two of the lithium ester enolates derived from (163) and (165) are both obtained with alkene geometry such that the alkyl group is trans to the enolate oxygen. It is also noteworthy that the two TMEDA-solvated enolates from (163) and (164) are dimeric, while the THF-solvated enolate from (165) exists as a tetramer. 

Another example of the nucleophilic chloro ligand substitution involves the reaction of the zirconium dichloride complex 468 with lithium ester enolates (Scheme 112). Its reaction with 2 equiv. of stable lithium ester enolates such as lithium tert-butyl isobutyrate in TF1F produces the bis(ester enolate) complex 499 as a crystalline solid.344 The same reaction but with the unstable lithium methyl isobutyrate leads to the isolation of the decomposition product, the bis(methoxide) complex 500, which exists as a dimer in the solid state. Treatment of the bis(ester enolate)... 

The acylal (4) can also be used to carry out reactions with nascent dimethylketene formed in situ. It is stable to t-butanol at the reflux temperature but with potassium carbonate present to ciitaly/,c cleavage it reacts smoothly to form /-butyl isobutyrate It reacts with an amine without other catalyst at room temperature to give an isohutyramide. In the presence of an alkali carbonate or the salt of a carboxylic acid, it converti an acid Into Its anhydride, probably via a mixed anhydride. With... 

This situation occurs in the presence of very low concentrations of tert. ROLi or of special activators (e. g. methyl or butyl isobutyrate). It is also induced in the presence of strongly solvating solvents (e. g. THF).
