, p. 396 - 400 (2009)
The kinetics of reactions of palladium(II) acetate with cobalt(II), nickel(II), and copper(II) acetates were studied by spectrophotometry. These reactions produce heterobimetallic complexes PdII(μ-OOCMe) 4MII(OH2/sub

The reactions of palladium(II) acetate with neodymium(III) and cerium(III) acetates in acetic acid containing a specified amount of water have been studied. The following homo- and heterometallic com- plexes have been synthesized and characterized by X-ray diffraction: Nd2(μ-OOCMe) 2(μ,η 2-OOCMe)2(η 2- OOCMe)2(HOOCMe)2(OH2)2 · 4HOOCMe, [Pd(μ-OOCMe)4Ce(OH2)2(μ,η 2-OOCMe)]2 · 2HOOCMe · 6H2O, [Pd(μ-OOCMe)4Ce(OH2)2(μ,η 2-OOCMe)]2 · 14H2O, [Pd(μ-OOCMe) 4M(HOOCMe)2(OH2)2]+ [Pd(μ-OOCMe)4M(μ- OOCMe)4Pd]- · 2MeCOOH · 1.5H2O (M = Nd, Ce), and {[Pd(μ- OOCMe)4Ce(OOCMe)4]2 [Pd4(μ-OOCMe)4]2(μ4-O) 8CePd4}(OH)3 · 27H2O. From kinetic and structural data and optical spectra of reaction solutions, the conclusion was drawn that hydrolytic processes play a decisive role in complexation reactions.

Synthesis and solution behavior of the trinuclear palladium(II) unsaturated carboxylate complexes triangle-Pd3[μ-O2CC(R′) = CHMe]6 (R′ = Me, H): X-ray structure of palladium(II) tiglate (R′ = Me)

The first examples of binary palladium(II) derivatives of unsaturated carboxylic acids are reported. It was found that the interaction of Pd3(μ-OAc)6 with the α,β-unsaturated 1-methylcrotonic (tiglic) and crotonic acids leads to the corresponding carboxylates of composition Pd3[μ-O2CC(R′) = CHMe]6, where R′ = Me (1) or H (2). The new compounds have been characterized by elemental analysis, solid and solution IR, 1H and 13C NMR, and ESI mass spectrometry. The crystal structure of 1 has been determined. This molecule displays a central Pd3 cyclic core with Pd-Pd distances of 3.093-3.171 A?. Each Pd-Pd bond is bridged by a pair of carboxylate ligands, one above and the other below the Pd3 plane, providing a square planar coordination for each Pd atom in an approximate D3h overall symmetry arrangement. Solution spectroscopic data show that the bridging η1:η1:μ2 interaction of the carboxylates of 1 and 2 is readily displaced, with a change of the ligand to the terminal (η1) coordination mode.
Non-trivial behavior of palladium(II) acetate

, p. 1989 - 1992 (2005)
Reaction of activated palladium metal with a HNO3/acetic acid mixture produces both orange Pd3(OAc)6, 1, and purple Pd3(OAc)5(NO2), 2. Compound 2 has a trinuclear structure derived from that of the well-known triangular complex 1 in which one acetate group has been replaced by a nitrite group which is bonded to one palladium atom by the nitrogen atom and to another Pd atom using one of the oxygen atoms. Highly pure 1 can be made by continuous removal of the nitric oxides from the reaction mixture using a flow of N2. 1H NMR spectra of solutions of 1 in CDCl3 and C6D6 show several signals of various intensities when a small amount of water is present in the deuterated solvents but only one signal when the solvents are thoroughly dried. These results are consistent with the occurrence of one or more hydrolysis processes when the solvents contain water and suggest that hypotheses about various [Pd(OAc)2]n aggregates that have previously been brought forward in the literature to explain the complexity of the spectrum of 1 are unnecessary, especially for nonpolar solvents. Compound 2 does not hydrolyze, and in wet or dried solvents shows a 1H NMR spectrum that consists of five equal-intensity signals due to the five nonequivalent acetate groups.

METHOD FOR PRODUCING ESTER COMPOUND AND PALLADIUM CATALYST USED IN THE METHOD
-
, (2015/12/24)
A method for producing an ester compound includes reacting a compound having at least one cyclic structure of a norbornene ring and a norbornadiene ring with an alcohol and carbon monoxide by using a palladium catalyst and an oxidizing agent, to thereby introduce ester groups to carbon atoms forming a double bond in the cyclic structure and obtaining the ester compound, wherein the palladium catalyst includes a palladium acetate having a nitrite ligand in an amount of 10% by mole or more in terms of metal, and the palladium acetate having a nitrite ligand is represented by the general formula (1): Pd3(CH3COO)5(NO2).
Palladium(II) acetates: Synthesis and molecular transformation scheme
Mulagaleev,Kirik
, p. 2065 - 2075 (2011/05/07)
Known methods for synthesis of a trinuclear molecular form of palladium(II) acetate, [Pd3(CH3COO)6], are analyzed and a number of new techniques that enable reliable control over the type of the product obtained and provide its high yield are suggested. A molecular transformation scheme is suggested. This scheme takes into account the formation of both forms of palladium acetate and also the formation of the structurally similar [Pd3(CH3COO)3NO2].
