Abstract

1724 Chemistry Letters, 19 8 4 Similar to the palladium catalyzed reactions, these rearrangements can be explained by the formation of тт-allyl complexes as intermediates, followed by decarboxylation, and intramolecular allylation of ketone enolate complexes 3. In addition to the decarboxylative allylation, we observed the palladium-catalyzed decarboxylative dehydrogenation of 1 and 2 to give a,ß-unsaturated ketones by using MeCN as a solvent.6-8' However, we ...
