Normal pressure carbonylation of cis-[M-(C6X5)2(OC4H 8)2] (M = Pd, Pt; X = F, Cl; OC4H8 = tetrahydrofuran) leads to the isolation of cis-[M(C6X5)

The action of CO on the solvento-complexes cis-[PdR2(thf) 2] [R = C6F5 (1), C6Cl5 (2)] at low temperature gives cis-[PdR2(CO)2] [R = C 6F5 (3), C6Cl5 (4)] in good yield by simple replacement of the highly labile thf molecules. These are rare cases of PdII dicarbonyl compounds, whose characterization relies on spectroscopic and analytic data. The crystal structure of the square-planar platinum homologue cis-[Pt(C6Cl5)2(CO) 2] is also presented. CO can split the double bridging-system in the dinuclear species [{PdR2}2(μ-X)2] 2- giving the homologous series of anionic monocarbonyl Pd II derivatives with formula [cis-PdR2X(CO)]- (5-10: R = C6F5, C6Cl5; X = Cl, Br, I), which were isolated (except for the R = C6F5 and X = I) and suitably characterized. Characterization includes the crystal and molecular structure of [PPh3Me][cis-Pd(C6F 5)2Br(CO)] (6′). The anionic species [NBu 4][cis-Pd(C6F5)2Cl(CO)] (5) reacts with neutral cis-[Pd(C6F5)2(CO)2] (3) under CO extrusion, affording the dinuclear derivative [NBu 4][{Pd(C6F5)2(CO)} 2(μ-Cl)] (11), which contains a single unsupported halide bridge (X-ray diffraction). Complex 11 can be considered as modelling a possible intermediate step in intermolecular CO substitution reactions that are easily undergone by PdII halo carbonyl species.

The enhanced stability of the metal-to-carbon bond M-R (M equals Au, Pt) when R is a polyhalophenyl group (R equals C//6F//5, C//6F//3H//2, C//6Cl//5) allows the isolation of neutral, cationic or anionic aryl derivatives fo both metals, which are excellent precursors for the synthesis of polynuclear compounds or mixed clusters with unusual structures and properties. On the other hand, stable solutions of the neutral complexes MR//2L//2 (M equals Pd, Pt; R equals C//6F//5, C//6Cl//5; L equals OC//4H//8) are a suitable source for the preparation of otherwise inaccessible compounds.
