57 Fe Moessbauer spectroscopic data for a series of 1,1′-bis(diphenylphosphino)ferrocene metal complexes (X= halide or CO, n=2 or 4) are reported.An approximately linear correlation was found between the isomer shift (delta) and the quadruple splitting (Delta).Moreover, complexes of like co-ordination geometry fell within exclusive domains on a plot of delta vs. Delta.The results of an analysis of available crystal-structure data are consistent with these observations.The Moessbauer hyperfine interaction are discussed in relation to the geometry of the co-ordinated metal.

Comparison with the known characteristics of isomeric pores with the common 13,23,32,4 3,52,63,72,83-sequence indicates that the self-assembly and the supramolecular chirality of rigid-rod beta-barrels are independent of the substitution pattern of the p-octiphenyl stave.

A cross-coupling reaction of alkyltrifluorosilanes with aryl halides was achieved using a catalytic amount of tetrakis-(triphenylphosphine)palladium(0) and excess of tetrabutylammonium fluoride (TBAF) at 100C with high chemoselectitvity. Functional groups like nitro, ketone carbonyl, and formyl tolerated the coupling conditions. Because potassium(18-crown-6) alkyltetrafluorosilicates also underwent a cross-coupling reaction in the presence of an additional molar amount of TBAF, the active species of the coupling reaction was assumed to be pentacoordinate silicates. TBAF in excess was considered to be required for trapping the tetrafluorosilane produced in the catalytic cycle of the cross-coupling reaction.

A simple and efficient asymmetric synthesis of novel sp3-rich pyrrolidine chemical scaffolds over five steps starting from simple ketones is described. Key steps involve the use of tert-butanesulfinamide as a chiral auxiliary to perform an asymmetric Tsuji?Trost allylation, with subsequent cross-metathesis with an acrylate ester and reduction of the sulfinimine/cyclisation of the resulting amine giving the pyrrolidine scaffolds in high yields and diastereoselectivites. By removing the chiral auxiliary and functionalising the ester group, the resulting scaffold core can be further derivatised.

In homogeneous catalysis, the catalyst is in the same phase as the reactant. The number of collisions between reactants and catalyst is at a maximum.In a patent, 32005-36-0, name is Bis(dibenzylideneacetone)palladium, introducing its new discovery. Quality Control of Bis(dibenzylideneacetone)palladium

A mechanism, which is distinct from the traditional one when sodium alkoxide was used instead of tertiary amines, was proposed for the alkoxycarbonylation of aryl iodides. The catalytic cycle was composed of oxidative addition, subsequent ArPdOR formation, CO insertion to Pd-OR, and final reductive elimination of ArPdCOOR. The kinetic simultaneity of the formation of deiodinated side product from the aryl iodide and aldehyde from corresponding alcohol provided strong evidence for the existence of ArPdOR species. The observation of thioether, as the other competitive product in palladium catalyzed thiocarbonylation of aryl iodides and sodium alkylthiolate, also indicate the possibility of metathesis between ArPdl and sodium alkylthiolate. Preliminary kinetic studies revealed that neither oxidative addition nor reductive elimination was rate limiting. DFT calculation displayed preference for CO insertion into Pd-OR bond. The advantage of this novel mechanism had been demonstrated in the facile alkoxycarbonylation and thiocarbonylation. The ethoxycarbonylation of aryl iodides under room temperature and balloon pressure of CO in the presence of EtONa were examined, and good to high yields were obtained; the t-butoxycarbonylation reactions in the presence of t-BuONa were achieved, and the alkylthiocarbonylation (including the t-butylthiocarbonylation) of aryl iodides in the presence of sodium alkylthiolate were also investigated.

72287-26-4, Name is [1,1′-Bis(diphenylphosphino)ferrocene]dichloropalladium(II), belongs to catalyst-palladium compound, is a common compound. Computed Properties of C34H28Cl2FeP2PdIn an article, once mentioned the new application about 72287-26-4.

Treatment of the complexes [MCl2(DPPF)] (M=Pt or Pd) {readily prepared in high yield from [MCl2(DMSO)2] (M=Pt (cis-) or Pd (trans-) and DPPF in CHCl3} with two molar proportions of AgNO3 in H2O did not give the expected cation [M(DPPF)(H2O)2] 2+ in solution. Instead the unusual homobimetallic bridged complex [{M(mu-OH)(DPPF)}2](NO3)2 was formed as an insoluble solvolysis solid product. Hence, carboxylation by addition of carboxylate anions to the solution cannot be carried out by this method. In contrast, the complex [PtCl2(DPPF)] reacted readily with two molar proportions of AgOAc or one of Ag2{1,1?-(OOC)2fc} (fc=ferrocene-2H) in acetone to give the corresponding carboxylato complexes. Other carboxylato complexes were obtained from the reaction of the complexes [MCl2(DPPF)] and the K-salts of e.g. (COOH)2, CH2(COOH)2, and CH2CH2CH2C(COOH)2 in H2O. With few exceptions, neither the K- nor the Ag-salts of the acids Me3CCOOH and C6H11COOH react completely with [MCl2(DPPF)] in aqueous or non-aqueous solutions. However, the required products were obtained by displacement of DMSO from the corresponding carboxylato complexes by DPPF in CHCl3. All of the new carboxylato complexes and the solvolysis products were characterized physicochemically and spectroscopically. The X-ray structures of [Pt{(OOC)2}(DPPF)] and of [PtCl(NO3)(DPPF)] were determined, to obtain some additional information on the coordination mode of the unsymmetrical DPPF ligand in this type of complexes.

Synthetic Route of 21797-13-7, Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics.In a document type is Article, and a compound is mentioned, 21797-13-7, Tetrakis(acetonitrile)palladium(II) tetrafluoroborate, introducing its new discovery.

The alternating copolymerization of 3,3-dimethylallene with carbon monoxide was achieved using [Pd(PPh3)2(MeCN)2](BF4)2 as the catalyst. The use of bidentate phosphines resulted in drastically reduced yields. In order to gain insight into the copolymerization mechanism, the stepwise successive insertions of 3,3-dimethylallene and carbon monoxide into palladium-carbon bonds in the complexes, Pd(PPh3)2(Me)(Cl), [Pd(PPh3)2(C(O)-C6H4-Me-p)(MeCN)](BF4), and [Pd[(Dppp)(Me)(MeCN)](BF4) (Dppp: 1,3-bis(diphenylphosphino)propane), were studied. These studies, in turn, led to a novel living catalytic system which was used to synthesize a terpolymer with alt-allene-carbon monoxide and alt-ethene-carbon monoxide blocks.
