Studies of trinuclear palladium clusters by 31P NMR spectroscopy: Reactivity of [Pd3Cl(PPh2)2(PR3) 3][BF4] complexes (R = et or Ph) and the synthesis of [Pd3(PPh2)3(PR3) 3][BF4]

A study of the reactivity of the new palladium clusters [Pd3(μ-Cl)(μ-PPh2)2(PR3) 3][BF4] (R = Et or Ph) is described. The products are characterized mainly by 31P NMR studies, and these spectra are discussed in detail. The bridging chloride and terminal tertiary phosphine ligands are all labile, and, in particular, reaction with diphenylphosphine and p-toluidine leads to elimination of HCl and formation of [Pd3(μ-PPh2)3(PR3) 3][BF4] clusters. [Pd3(μ-PPh2)3(PPh3) 3]+ is also formed by reaction of [Pd(PPh3)4] with [Pd2Cl2(μ-PPh2)2(PHPh 2)2]. Reaction of [Pd3(μ-Cl)(μ-PPh2)2(PR3) 3][BF4] with H2O2 and HCl leads to a remarkable, stereospecific ring opening with oxidation of all the palladium atoms to PdII. The product, cis,cis,cis-[Cl(PR3)Pd(μ-PPh2)(μ-Cl)Pd(μ-PPh 2)(μ-Cl)PdCl(PR3)], reacts with 2 mol of PR3 to yield trans-[PdCl2(PR3)2] and [Pd2Cl2(μ-PPh2)2(PR 3)2]. This entire oxidative degradation sequence is almost quantitative.
