Allylation of /3-keto esters or malonates was carried out in good yields under neutral conditions by using allylic carbonates in the presence of palladium-phosphine catalyst. Although simple ketones, esters, nitriles, and sulfones hardly react with allylic carbonates, -alkenyl or -aryl ketones, esters, nitriles, and sulfones were also allylated by using palladium-bis(diphenylphosphino)ethane catalyst under neutral conditions.We have reported the reaction of (v-allyljpalladium chloride (1) with carbonucleophiles such as malonates, acetoacetates, and enamines as a new method for carbon-carbon bond formation1 (Scheme I, eq 1). Later, in situ formation of (T-allyl)palladium complexes 2 as in-
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
