Palladium-Catalyzed Aminocarbonylation of Cinnamyl N,N-Dialkylcarbamates. An Intriguing Crossover with p-Methylcinnamylamines

抄録

Competition experiments in the palladium-catalyzed aminocarbonylation of cinnamyl N,N-dialkylcarbamates with p-methylcinnamylamines revealed that the allylamine did not undergo oxidative addition but attacked extensively a π-allylpalladium which arose from the allyl carbamate under the conditions employed, forming a mixture of the corresponding amides containing either cinnamyl moiety that incorporates a dialkylamino component originated only from the carbamate.
