Darzens-Nenitzescu synthesis of ketones

What is Darzens-Nenitzescu synthesis of ketones?

The Darzens-Nenitzescu synthesis of ketones is a chemical process that involves the acylation of olefins using acid chlorides or anhydrides that are catalyzed by Lewis acids to produce ketones. When this synthesis is carried out in the presence of a saturated hydrocarbon, the resulting product is a saturated ketone.
