Heteropolymetallic Architectures as Snapshots of Transmetallation Processes at Different Degrees of Transfer.

ABSTRACT: Novel heteropolymetallic architectures have been built by integrating Pd, Au and Ag systems. The dinuclear [(CNC)(PPh₃ )Pd-^G11 M(PPh₃ )](ClO₄ ) (^G11 M=Au (3), Ag (4); CNC=2,6-diphenylpyridinate) and trinuclear [{(CNC)(PPh₃ )Pd}₂ ^G11 M](ClO₄ ) (^G11 M=Au (6), Ag (5)) complexes have been accessed or isolated. Structural and DFT characterization unveil striking interactions of one of the aryl groups of the CNC ligand(s) with the ^G11 M center, suggesting these complexes constitute models of transmetallation processes. Further analyses allow to qualitatively order the degree of transfer, proving that Au promotes the highest one and also that Pd systems favor higher degrees tha
