Stereochemistry of formation of (2–4η)-PdCl complexes from deuteriosubstituted 1-acetyl-4-t-butylcyclohex-1-enes
Abstract
The loss of 1H and 2H during the formation of (2–4η)-PdCl compounds from deuterio-substituted 1-acetyl-4-t-butylcyclohex-1-enes shows little stereoselectivity and is compatible with a mechanism of formation which involves an initial palladium-assisted enolisation of the enone.
