Abstract

Two palladium complexes containing triene-coordinated ligands, 3 and 4, open-chain analogues of the macrocyclic palladium(0) complexes of type 1, have been synthesized. A comparative study of both open-chain and macrocyclic complexes has been carried out, based on a NMR and X-ray structural analysis, a DSC thermal behavior assessment, and a catalytical activity evaluation in the arenediazonium and organotrifluoroborate cross-coupling Suzuki-Miyaura reaction. The 1,6,11-triene sequence has been revealed to be crucial in the great stability of this family of palladium(0) complexes. © 2008 American Chemical Society.
