The stereochemistry of organometallic compounds. XVII. Reactions of π-allylpalladium compounds with acetylacetone

Reactions of π-allylpalladium compounds with sodium acetylacetonate, sodium malononitrile, and sodium ethylacetoacetate in dimethyl sulfoxide solution give diallyl substitution products. Reaction of the acetylacetonate complexes with carbon monoxide in benzene give mono- allyl substitution products. Application of these reactions to the π- allyl complexes from 1-acetyl-4-t-butylcyclohex-1-ene and from 3-oxo 4- ene steroids in an attempt to examine the stereochemistry of ligand transfer gave no substitution products.
