(Received 21 September 2010; accepted 26 September 2010; online 2 October 2010)

In the title complex, [PdBr(C4H3N2)(C18H15P)2], the geometry around the PdII atom is distorted square-planar with the PdII atom displaced by 0.0150 (5) Å from the least-squares BrP2C plane. Two PPh3 ligands are in trans positions [P—Pd—P = 176.743 (17)°], while the pyrimidinyl ligand and Br atom are trans to one another [C—Pd—Br = 176.56 (5)°]. Structural parameters from NMR, IR and mass spectra are in agreement with the crystal structure of the title compound.

C—C coupling reactions of pyrimidinyl nickel complexes (Steffen et al., 2005), Suzuki cross-coupling reactions of pyridyl-bridged palladium complex (Beeby, et al., 2004), and intramolecular reductive elimination of Pd—N binuclear complex [Pd(µ-C9H6N)(µ-dppm)]2(Cl)2 (Chin et al., 1988) are some of important reactions in organic synthesis by forming C—C bond (Dobrzynski & Angelici, 1975). To our knowledge, no 2-palladiumpyrimidine crystal structure has been described.

To synthesis of 2-palladiumpyrimidine compound, complex [Pd(PPh3)4] was used to react with 2-bromopyrimidine in dichloromethane at room temperature. As a result, a two triphenylphosphine displaced complex [Pd(Br)(C4H3N2)(PPh3)2] was isolated with 95% yield. The X-ray crystal structure analysis has been carried out to provide structural parameters.

The molecular structure of the title compound is shown in Fig. 1. In the title complex (I), the palladium atom has a distorted square planar geometry. The palladium atom is displaced by 0.0150 (5)Å from the least-squares plane of BrP1P2C1. The Pd—C1 bond distance, 1.9985 (18) Å, is longer than other PdII-carbon(carbonyl) distances, and similar to those of Pd—C(carbene) distances (Cardin et al., 1972, and references therein). Two PPh3 ligands are in trans position: P1—Pd—P2, 176.743 (17)°, while the pyrimidinyl ligand and bromide are trans to each other: C1—Pd—Br1, 176.56 (5)°. The Pd—N bond distances (2.8489 (17) and 2.8703 (16) Å) indicate no bonding interaction between the nitrogen atom and palladium metal atom. Within the pyrimidinyl ligand itself, the geometry is consistent with a significant partial double bond character in the C—C and C—N bond. The C—N bond distances (1.330 (2) ~1.340 (3) Å) are typical for a C—N bond having partial double bond character and are certainly much shorter than the normal C—N (1.47 Å) single bond. The Pd—C1 (1.9985 (18) Å) and Pd—Br (2.5353 (3) Å) lengths of (I) are in agreement with reported value (Yih et al., 2008, 2009).

The 31P{1H} NMR spectra of (I) shows a singlet resonances at δ 21.4. In the 1H NMR spectra, the 4-H and 5-H protons of the pyrimidinyl group exhibit two singlet resonances at δ 7.86 and at δ 7.52. The 13C{1H} NMR spectra of (I) reveals two singlet at δ 114.2 and at δ 154.4 which are assigned to the 5-C and 4-C carbon atom of the pyrimidinyl group. It is also noted the IR spectrum of the title complex (I) shows two stretching bands at 1546 and 1537 cm-1 for C═N groups. In the FAB mass spectra, base peak with the typical Pd isotope distribution is in agreement with the [M+] molecular mass of (I).

Experimental top

The synthesis of the title compound (I) was carried out as follows. 2-Bromo-pyrimidine (0.191 g, 1.2 mmol) was added to a flask (100 ml) containing Pd(PPh3)4 (1.155 g, 1.0 mmol) and CH2Cl2 (20 ml) at ambient temperature. The mixture was stirred for 2 h. The solvent was concentrated to 10 ml, and 20 ml of diethyl ether was added to the solution. The pale-yellow solids were formed which were isolated by filtration (G4), washed with n-hexane (2 x 10 ml) and subsequently dried under vacuum yielding 0.750 g (95%) of the complex [Pd(PPh3)2(C4H3N2)Br], (I). Spectroscopic data for (I): 31P{1H} NMR: δ 21.4 (s, PPh3). 1H NMR: δ 7.23–7.66 (m, 30H, 2PPh3), 7.52 (s, 1H, 5-H of pyrimidinyl), 7.86 (s, 2H, 4-H of pyrimidinyl). 13C{1H} NMR: δ 128.0 (m, o-C of Ph), 129.9 (m, p-C of Ph), 134.8 (m, m-C of Ph), 114.2 (s, 4-C of pyrimidinyl), 154.4 (s, 5-C of pyrimidinyl). MS (FAB, NBA, m/z): 789 [M+]. Anal. Calcd. for C40H33BrN2P2Pd: C, 60.82; H, 4.21; N, 3.55. Found: C, 60.94; H, 4.31; N, 3.18.

Structure description top

C—C coupling reactions of pyrimidinyl nickel complexes (Steffen et al., 2005), Suzuki cross-coupling reactions of pyridyl-bridged palladium complex (Beeby, et al., 2004), and intramolecular reductive elimination of Pd—N binuclear complex [Pd(µ-C9H6N)(µ-dppm)]2(Cl)2 (Chin et al., 1988) are some of important reactions in organic synthesis by forming C—C bond (Dobrzynski & Angelici, 1975).

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.
