✦ Synopsis

Pd(O)= and Pd(II)-complexes catalyze many isomerization reactions in which an ally1 group migrates from one position in a molecule to another. Examples are the Pd(II)-catalyzed Cope rearrangement1 of 1 ,S-dienes

The observation of practically identical activation parameters for the Cope rearrangement 2 Ǟ 6 and its "frustrated" counterpart 1 Ǟ 5 indicates a two-step mechanism for the reaction 2 Ǟ 6. Direct proof of this interpretation comes from trapping experiments, which demonstrate the intermediate format

Pd(0) complexes catalyze the 3-Aza-Cope rearrangement of N-allylenamines to the corresponding 6,c-unsaturated imines or y,+unsaturated carbonyl compounds in the presence of trifluoroacetic acid as co-catalyst. The Cope rearrangements are of considerable synthetic utility. There have been many report
