Stability of metal-metal interactions in dinuclear Pt-Au complexes as a function of bridging Pt-arene ring electronics.

ABSTRACT: A series of dinuclear Pt-Au complexes [(bhq-Ph^R)(PPh₃)Pt-Au(PPh₃)]⁺ (R = -H (5), -OMe (5-OMe), -F (5-F), and -CF₃ (5-CF3)), derived from novel Pt complexes (4, 4-OMe, 4-F, and 4-CF3), were prepared and analyzed using solution-state NMR spectroscopy and X-ray crystallography. The persistence of three-center Pt-Au-C_ipso bonding interaction in solution and the migration of [Au(PPh₃)]⁺ across electronically distinct arenes of 5, 5-OMe, 5-F, and 5-CF3 offers a unique opportunity to probe the intermediates of transmetallation as a function of bridging arene ring electronic properties. Analysis of the solid-state X-ray structures of these dinuclear complexes reveal that the degree of arene ring transfer
