The palladium(II) chlorostibine complex [PdCl2(SbMe2Cl)2]2 has a dimeric structure in the solid state, stabilized by hyper-coordination at the Lewis amphoteric Sb centers. Reaction with 8 equiv of MeLi forms [Pd4(μ3-SbMe3)4(SbMe3)4], whose structure comprises a tetrahedral Pd(0) core with four terminal SbMe3 ligands and four μ3-SbMe3 ligands, one capping each triangular Pd3 face. Density functi...

In the title compound, [PdCl2(C15H11NO3)2]·CHCl3, the Pd(II) atom adopts a slightly distorted square-planar coordination geometry composed of two Cl atoms in cis positions and two C atoms from isocyano-phenyl ligands. The mol-ecular conformation is stabilized by π-π stacking inter-actions [shortest centroid-centroid distance = 3.600 (1) Å] between substituted benzene rings of different ligands....

The synthesis of 2-α-styrylpyridines has been carried out by using the coupling of polyoxygenated N-tosylhydrazones with various 2-halopyridines. We demonstrated that the use of a catalytic amount of PdCl2(MeCN)2 in combination with a bidentate ferrocene DPPF or a monodentate alkyl phosphine (t)Bu2MeP-HBF4 constitutes an efficient protocol for this coupling, providing 2-α-styrylpyridines 2 in s...

Selective reduction of NOx by H2 and CO in excess O2 was studied using a Pd/Al2O3 catalyst. Incipient wetness impregnation into Al2O3 was done using PdCl2 as the metal precursor. The NOx conversion profile was maximal at 423 K (up to 95.2% for 250 ppm CO), at which temperature complete oxidation of H2 and CO occurred. There is a very strong synergic effect when both CO and H2 are simultaneously...

[reaction: see text] The 1-fluoro-1-haloalkenes undergo Pd-catalyzed Negishi cross-couplings with primary alkylzinc bromides to give multisubstituted fluoroalkenes. The alkylation was trans-selective giving pure Z-fluoroalkenes in most cases. The highest yields were obtained with Pd2(dba)3 and PdCl2(dppb) catalysts but the best stereochemical outcome was obtained with less reactive Pd(PPh3)4. T...

Copper-catalyzed cross-coupling of ferrocenyl ketone-derived N-tosylhydrazones with benzo[d]oxazole leads to the direct C-H bond functionalization by a secondary ferrocenyl alkyl group. This direct C-H bond alkylation of azoles with N-tosylhydrazones bearing a ferrocenyl group uses inexpensive CuBr as the catalyst without any ligand. The reaction is operationally simple and conducted under mild...

2-Methylprop-2-ene-, prop-2-ene-, 1-methylprop-2-ene-, and (E)-but-2-enesulfonyl chlorides have been used as electrophilic partners in desulfinylative palladium-catalyzed C–C coupling with Grignard reagents and sodium salts of dimethyl malonate and methyl acetoacetate. Neopentyl alk-2-ene sulfonates can also be used as electrophilic partners in desulfinylative allylic arylations and allylic alk...

The asymmetric unit of the title compound, [PdCl2(C10H8N2)]·0.5C4H8O2, consists of one Pd(II) complex mol-ecule and a half-mol-ecule of 1,4-dioxane, the complete mol-ecule being generated by inversion symmetry. The Pd(II) atom has an almost square-planar coordination formed by the 2,2'-bi-pyridine ligand and two chloride ligands. Two intra-molecular C-H⋯Cl hydrogen bonds occur. In the crystal, ...

The title complex salt, (C12H16NO2)[PdCl2(C12H14NO2)], is of inter-est with respect to organic and organometallic catalysis. The compound crystallizes as very small orange-red irregular prisms and the asymmetric unit contains three crystallographically distinct cation-anion pairs. The coordination geometry about the palladium atoms is square-planar with the chloride ligands cis to one another. ...
