Abstract:

Bisiminophosphorane palladacycles were synthesized efficiently through the cyclometallation process providing tetranuclear palladium species with macrocycle-type structures. These ensuing compounds were reacted with different bidentate ligands in a 1:4 ratio. The results showed that only bimetallic complexes with two chelating ligands were obtained. This puts forward that the chelate effect predominates in this process over the macrocycle effect.
