The Pd(II)complexes [Pd(acac)(PR3)(PhCN)][BF4] and [Pd(acac)(S)2][BF4] (acac = acetylacetonate; R = phenyl, 2-methoxyphenyl; S = benzonitrile, pyridine, CD3CN) were synthesized by the reaction of Pd(a

A series of novel [Pd(acac-O,O′)(P?P)]BF4 and known complexes [Pd(acac-O,O′)(PR3)2]BF4 (P?P = dppm (1), dppp (2), dppb (3), dppf (4); R = Ph (5), p-Tol (6), i-Pr (7); acac = 2,4-pentanedionato) were prepared by the reaction of [Pd(acac-O,O′)(MeCN)2]BF4 (1) with appropriate ligands. Complex 2 was characterized by single-crystal X-ray analysis. Models of the structure and IR wavenumbers assignments of the cations of 1-4 were obtained by DFT calculations. Synthesized complexes were tested as catalysts in the telomerization of isoprene and butadiene with diethylamine. In the case of telomerization of butadiene with diethylamine high catalyst activity (e.g. TOFav = 1940 h-1 and TON up to 17,480 for complex 5) was obtained.

, p. 752 - 756 (2011)
An X-ray diffraction analysis is carried out for the complex [Pd(Acac)(PPh3)2]BF4 (I), which is a precursor of the active complexes of styrene dimerization and norbornene additive polymerization in the system [(Acac)Pd(PPh3)2]BF 4-BF3 ? OEt2. In complex I the palladium atom is coordinated by two oxygen atoms of the acetylacetonate ligand and two phosphorus atoms of the triphenylphosphine ligands at the vertices of the distorted square.

The interaction between the components of a catalytic system Pd(acac)(C3-acac)PPh3 + nPPh3 + mBF3OEt2 (where n = 1-4, m = 0.25-4, and acac is the acetylacetonate ligand) in benzene is examined by UV and IR spectroscopy. With a relative excess of PPh3 (n > m), acacH and [Pd(acac)(PPh3)2]+BF-4 were the main products, whereas BF2acac and a polynuclear complex of PdF2 with PPh3 also containing Pd2+(BF-4)2 units were formed with a relative excess of BF3OEt2 (n m).

A series of palladium complexes of general formula [(Acac)PdL1L2]+A-, where L1, L2 = phosphines and A = BF4, CF3SO3, were synthesized. Preliminary studies show that the complexes are active in selective dimerization of styrene and addition polymerization of norbornene.
Dicationic tetrakis(triphenylphosphine)palladium(II) and tetrakis(triphenyl phosphite)palladium(II) complexes
Yamazaki, Shinsaku
, p. 1638 - 1640 (2008/10/08)
The synthesis and properties of the cationic palladium(II) complexes are described. Dicationic [Pd(PPh3)4](X)2 (X = BF4-, PF6-) and [Pd(P(OPh)3)4](PF6)2 have been prepared by the reaction of Pd(PPh3)4 with CPh3X (X = BF4-, PF6-). A pentacoordinated Pd(II) complex of the heterocyclic ligand 1,10-phenanthroline, [Pd(1,10-phen)2(PPh3)](X)2) was obtained from the reaction of [Pd(PPh3)4](X)2 with 1,10-phen. Monocationic [Pd(CH3COCHCO-R)(PPh3)2](X) (R = Me, OMe) has been isolated from the reaction of Pd(PPh3)4 with CPh3X in the presence of acetylacetone or methyl acetoacetate. Likely structures and some features for these new complexes are proposed from 1H NMR and IR spectrometry.
