The relative reactivities of allylic and propargylic acetates toward palladium (0)-catalyzed substitution by various nucleophiles were studied by using three types of model substrates:(a) monofunctional allylic and propargylic acetates with similar structural properties;(b) a bifunctional substrate containing both allyl and propargyl functionalities with no apparent interaction between them;(c) conjugated bifunctional systems, in which the ...
