Abstract :
Cycloisomerization of 1,6-enynes is successfully carried out in the presence of a dicationic platinum(IV) catalyst to afford five-membered ring systems. The use of a weakly coordinating axial ligand is the key to bringing out the catalytic activity of platinum porphyrin for the reaction.
