A route to trinuclear platinum-gold clusters

New A-frame cluster complexes have been prepared by addition of electrophilic gold fragments to the Pt-Pt bond of , dppm = Ph2PCH2PPh2.For example, gave and gave NO3.The complexes reacted with to give BF4 when n = 1 or 2, but the bridged bis(A-frame) cluster complex 2CH2>(BF4)2 when n = 3.In contrast, CuCl reacted with to give .Attempts to synthesize A-frame clusters containing Pt2Ag, Pt2Cu, Pd2Au, or PdPtAu units were unsuccessful, and it is concluded that these units are considerably weaker than the analogous 3-center 2-electron bond of the Pt2Au unit.The AuCl unit is displaced from on reaction with diazomethane, with formation of .Key words: platinum, gold, cluster, copper, silver.

Ligand substitution reactions of a dinuclear platinum (I) complex

The complex Pt2Br2(μ-dppm)2 reacts with Et4NCl in dichloromethane and dichloroethane to form Pt2Cl2(μ-dppm)2. The reaction is reversible and proceeds via stepwise formation of the mixed-ligand (Br, Cl) complex. The reaction follows biphasic kinetics, and each step shows a linear dependence on [Et4NCl], with rate constants 93 ± 20 and 19.4 ± 1.2 M-1 s-1 for the respective steps (10.0°C in CH2Cl2). The identification of a rate constant with an individual step is a process that inherently admits of dual solutions; the assignment of k1 = 93 M-1 s-1 and k2 = 19.4 M-1 s-1 was made on the basis that only this model gave a consistent and reasonable value for the molar absorptivity of the mixed-halide intermediate. The reaction in 1,2-dichloroethane shows a quite different kinetic pattern, with a single pseudo-first-order rate law and a more complex variation of kobsd with [Et4NCl].

Binuclear reductive elimination reactions in diplatinum complexes: Synthesis of hydridoplatinum(I) complexes

The complex [Pt2H2(μ-H)(μ-dppm)2][PF6] (1) (dppm = Ph2PCH2PPh2) reacts with tertiary phosphine ligands to give H2 and the hydridoplatinum(I) complexes [Pt2HL(μ-dppm)2][PF6] (4, L = η1-dppm; 5, L = PMe2Ph; 6, L = PMePh2; 7, L = PPh3). Complex 4 is also obtained by the reduction of [Pt(dppm)2][PF6]2 with sodium borohydride. Study of the 1H and 31P NMR spectra of 4-7 is in accord with the presence of Pt-Pt bonds and, in the case of 4, shows that its structure in solution is similar to that previously determined in the solid state by an X-ray investigation. Methanethiol reacts reversibly with 4 to give [Pt2H2(μ-SMe)(μ-dppm)2][PF6]. Attempts to prepare diplatinum(0) complexes by deprotonation of 4 or 7 were unsuccessful.
