This paper describes the synthesis of a series of PdIV complexes containing modular monoanionic tridentate facially coordinated NNN and NNC donor ligands. In all cases, these complexes are stable to reductive elimination for a minimum of several days in solution at room temperature. With appropriately designed tridentate ligands, the PdIV adducts participate in both ligand substitution and C-H activation reactions. Overall, this work shows that unsymmetrical fac-L2X type ligands can serve as versatile and tunable scaffolds for modulating the reactivity of octahedral PdIV complexes.

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.

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.

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.
