Metal-metal bonded homo- and heterobimetallic compounds of Pt(I) and Pd(I) supported by a bridging-N,P:N′,P′ moiety of a potentially hexadentate ligand

Reactions of metal-metal bonded homobimetallic (Pd2) and heterobimetallic (PtPd) complexes, supported by a P,P′-bridging-bis(P,N- chelating) coordination mode of the potentially hexadentate ligand 1,1-bis[di(o-N,N-dimethylanilinyl)phosphino]methane (dmapm), with CO, diethylacetylenedicarboxylate (DEAD), and thiols (RSH) in CH2Cl 2 are described. At room temperature, rac-Pd2Cl 2(μ-N,P:P′,N′-dmapm) gives the stable complexes Pd2Cl2(μ-CO)2-(μ-P.P′-dmapm) and PdCl(η2-DEAD)(μ-P:P′,N-dmapm)PdCl (which is fluxional in solution), while rac-PtPdCl2(μ-N,P:P′,N′-dmapm) disproportionates to PtCl2(P,P′-dmapm) and Pd metal, although at low temperature intermediate carbonyl species are detected in the CO reaction. The reactions with thiols in the presence of triflic acid (HOTf) generate rac-[MPdCl2(μ-SR)μ-N,P:P′,N′-dmapm)][OTf] and H2 for both M = Pt and Pd. In CH2Cl2, PdX2(dmapm) species (X = halide or CN) exist as equilibrium mixtures of P,P′- and P,N-ligated forms. For X = Cl, the P,P′-P,N equilibrium is governed by ΔH° = -5.5 ± 0.5 kJ mol-1 and ΔS° = 10 ± 1 J mol-1 K-1, and the ring-strain energy within the P,P′-isomer is ～32 kJ mol-1; the equilibrium increasingly favors the P,N-form with X = CN ? I > Br > Cl. The solid-state structures of rac-[PtPdCl2(μ-SEt)(μ-N,P: P′,N′-NP:P′,N-dmapm)][OTf] and PdCl2(P,N-dmapm) are presented; the latter contains both bound and free N- and P-atoms of identical types in the same molecule and permits an assessment of σ- and π-bonding between these atoms and Pd.
