Intramolecular cyclization of π-1-chloro-3-phenylallylpalladium( II ) complexes. A novel route to stable indenyl complexes of palladium( II )

Intramolecular cyclization of the π-allylpalladium(II) complexes derived from the reaction of [(Ph–CN)2PdCl2] with tri- and tetra-substituted cyclopropenes affords novel indenylpalladium(II) complexes with and without strong donor ligand activation.
