Reaction of unsaturated (44e- skeleton) [PdPt 2(μ-PPh2)2(μ-P2Ph 4)(RF)4] 4 with Br- produces the saturated (48e- skeleton) complex [NBu4][(R F)2Pt(μ-PPh2)(μ-Br)Pd(μ-PPh 2)(μ-P2Ph4)Pt(RF)2] 5 without any M-M′ bond. Attempts to eliminate Br- of 5 with Ag+ in CH2Cl2 as a solvent gives a mixture of [(RF)2PtIII(μ-PPh2) 2PtIII(RF)2] and some other unidentified products as a consequence of oxidation and partial fragmentation. However, when the reaction of 5 with Ag+ is carried out in CH 3CN, no oxidation is observed but the elimination of Br- and the formation of [(RF)2(CH3CN)Pt(μ- PPh2)Pd(μ-PPh2)(μ-P2Ph 4)Pt(RF)2] 6 (46e- skeleton), a complex with a Pt-Pd bond, takes place. It is noteworthy that the reaction of 5 with TIPF6 in CH2Cl2 does not precipitate TlBr but forms the adduct [(RF)2PtTl(μ-PPh 2)(μ-Br)Pd(μ-PPh2)(μ-P2Ph 4)Pt(RF)2] 7 with a Pt-Tl bond. Likewise, 5 reacts with [AgOClO3(PPh3)] in CH2Cl 2 forming the adduct [AgPdPt2(μ-Br)(μ-PPh 2)2(μ-Ph2P-PPh2)(R F)4(PPh3)] 8, which contains a Pt-Ag bond. Both adducts are unstable in a CH3CN solution, precipitating TlBr or AgBr and yielding the unsaturated 6. The treatment of [NBu4] 2[(RF)2Pt(μ-PPh2) 2Pd(μ-PPh2)2Pt(RF)2] in CH3CN with I2 (1:1 molar ratio) at 233 K yields a mixture of 4 and 6, which after recrystallization from CH2Cl 2 is totally converted in 4. If the reaction with I2 is carried out at room temperature, a mixture of the isomers [NBu 4][(RF)2Pt(μ-PPh2)(μ-I) Pd(μ-PPh2)(μ-P2Ph4)Pt(RF) 2] 9 and [NBu4][(RF)(PPh2R F)Pt(μ-PPh2)(μ-I)Pd(μ-PPh2) 2Pt(RF)2] 10 are obtained. The structures of the complexes have been established on the bases of NMR data, and the X-ray structures of 5-8 have been studied. The relationship between the different complexes has been studied.

Reversible transformation of two diphenylphosphanido ligands into the neutral tetraphenyldiphosphane ligand

(Chemical Equation Presented) From a theoretical prediction to an experimental finding: Oxidation of two bridging diphenylphosphanido ligands to a neutral tetraphenyldiphosphane is predicted theoretically and achieved experimentally in a trinuclear Pt2Pd complex (see scheme, R F = C6F5, P* = PPh2).
