[Butyllithium]

Hi, all,
In the following reaction, a nucleophilic addition reaction between carbon anions prepared in situ and acetone was figured. I want to know the nucleopilicity of this kind of carbonanion via de-silication type reaction in situ. And some kind of electrophilic group, such as lactones,esters,cyanides,imides, or other electrophilic reagents can tolerate it?
Thanks in advance.

Do you have an excess of TBAF to determine the kinetics? Which solvent do you use?
