ABSTRACT:
Keto compounds are prepared by a condensation reaction in which an enolate is formed, and then a protonation in which the free keto compound is produced. In accordance with the invention, both condensation and protonation are carried out in one step by electrodialysis. Transesterification can also be carried out in the same step.
