Acylpalladium derivatives intermolecular reactions

Also in 1986, intermolecular versions of the reaction of putative acylpalladium derivatives with the enolates derived from malonic esters and a few ketones were independently reported, Two different courses of reaction were observed with malonate esters (Scheme 3). However, both involve selective C-acylation. In cases where the C-acylation products, which are /S-keto diesters, still contain an acidic /3 C—H bond, they will further react with acylpalladium derivatives as 0-enolates rather than C-enolates, as detailed in the following section.
