(Received 23 September 2009; accepted 6 October 2009; online 10 October 2009)

The structure of the title compound, [PdCl2(C21H21O3P)2], shows a nearly square-planar geometry for the PdII atom within the Cl2Pd[P(PhOMe)3]2 ligand set. The PdII atom sits on a centre of inversion and therefore the asymmetric unit contains one half-mol­ecule, i.e. half of one PdII atom, one Cl atom and one tris­(2-methoxy­phen­yl)phosphine ligand.

Comment top

The palladium-catalysed methoxycarbonylation (Robertson and Cole-Hamilton, 2002) of 1-alkenes is an active area of research. The preferred (pre)-catalysts of general structure (Ar3P)2PdX2 (X = Cl, DMS, OTf etc.) are either preformed or generated in situ. The x-ray structures (Van Leeuwen et al., 2003 and Williams et al., 2008) of several of this class of palladium(II) complexes have been determined. Only some of these have found application in the catalysis of the methoxycarbonylation reaction, but their use results mainly in the formation of linear esters (Robertson and Cole-Hamilton, 2002). However, we have identified some palladium(II) complexes which catalyse the regioselective formation of branched esters. We report here the structure of one of these.

The structure of the title compound, [PdCl2(C42H42P2O6)], (I), shows a nearly square planar geometry (Table 1.) for the PdII atom within the Cl2(P(PhOMe)3) ligand set. The palladium atom sits on a centre of inversion and therefore the the asymmetric unit contains the half of the molecule, i.e. half of the palladium atom, one chlorine atom and one tris-(2-methoxyphenyl)phosphine ligand (Figure 1.)

Experimental top

Starting ligand material, tris-(2-methoxyphenyl)phosphine (1.408 g, 4 mmol) was added to a solution of palladium(II) chloride (1.288 g, 2 mmol) and anhydrous lithium chloride (168 mg, 4 mmol) in 15 ml methanol. The mixture was stirred under reflux in an atmosphere of nitrogen until all the phosphine reagent had reacted and a yellow product had formed (ca 1 hr). The reaction mixture was cooled and the product collected by filtration; washed with fresh methanol and dried under vacuum. The crude product (1.41 g) was dissolved in dichloromethane and crystallization of the title compound was carried out by diethyl ether vapor diffusion into the dichloromethane. The crystals of the title compound were bright yellow prisms (m. p. > 222° C, decomp.) and a suitable crystal was selected for the single-crystal X-ray diffraction analysis.

Refinement top

H atoms were geometrically positioned and refined in the riding-model approximation, with C—H = 0.93-0.96 Å, and Uiso(H) = 1.2Ueq(C) or 1.5Ueq(C for Me). For (I), the highest peak in the final difference map is 1.01 Å from Pd1 and the deepest hole is 0.01 Å from Pd1.

Special details top

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
