3375-31-3 Usage

Reactions

Efficient catalyst for the arylation of olefins (Heck reaction). Catalyst for cross-coupling reactions. Catalyst for C-H activation. Precatalyst for enantioselective decarboxylative protonation of allyl β-ketoesters.

Chemical Properties

brown needles

Uses

Different sources of media describe the Uses of 3375-31-3 differently. You can refer to the following data:
1. suzuki reaction
2. Palladium (II) Acetate Trimer is used in Suzuki-Miyaura cross-coupling reactions. It also serves to catalyze the chemoselective reduction of nitroarenes.
3. A catalyst for intramolecular coupling.

General Description

Palladium(II) acetate is a homogenous oxidation catalyst. It participates in the activation of alkenic and aromatic compounds towards oxidative inter- and intramolecular nucleophilic reactions. Crystals of palladium(II) acetate have a trimeric structure, having symmetry D3h. Each of the palladium atoms in the crystals are joined to the other two by double acetate bridges. Microencapsulation of palladium(II) acetate in polyurea affords polyurea-encapsulated palladium(II) acetate. It is a versatile heterogeneous catalyst for various phosphine-free cross-coupling reactions. It participates as catalyst in the Heck coupling reaction of pthalides with different alkenes.

Flammability and Explosibility

Nonflammable

Safety Profile

Moderately toxic by ingestion. When heated to decomposition it emits toxic vapors of palladium.

Purification Methods

It recrystallises from CHCl3 as purple crystals. It can be washed with AcOH and H2O and dried in air. Large crystals are obtained by dissolving it in *C6H6, adding half its volume of AcOH and allowing it to evaporate slowly at room temperature. It forms green adducts with nitrogen donors, it dissolves in KI solution to form solid PdI2 and a red solution of PdI42-, but is insoluble in aqueous saturated NaCl, and NaOAc. It dissolves in HCl to form PdCl42-. It is soluble in CHCl3, CH2Cl2, Me2CO, MeCN, Et2O, but it is insoluble in H2O, and decomposes when warmed in alcohols in which it is also insoluble.

Check Digit Verification of cas no

The CAS Registry Mumber 3375-31-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,3,7 and 5 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 3375-31:
(6*3)+(5*3)+(4*7)+(3*5)+(2*3)+(1*1)=83
83 % 10 = 3
So 3375-31-3 is a valid CAS Registry Number.

The Mechanism and Kinetic Models of the Catalytic Oxidation of Ethylene by p-Benzoquinone in Aqueous–Acetonitrile Solutions of Pd(II) Cationic Complexes

Martynov,Efremov,Bovyrina,Katsman,Temkin

, p. 436 - 443 (2018)

A kinetic study of ethylene oxidation to acetaldehyde by p-benzoquinone in the Pd(OAc)2–HClO4?LiClO4–CH3CN–H2O system has been carried out under conditions when palladium(II) cationic complexes exist at a molar fraction of water of 0.67 and 30°С. For a reaction that mostly lead to the formation ofPd(CH3CN)(H2O)32+ two-route mechanism and a kinetic model have been proposed that describe adequately the experimental dependence of the reaction initial rate on the concentration of p-benzoquinone, HClO4, and palladium. The model takes into account previous findings on the H2O/D2O and C2H4/C2D4 kinetic isotope effects and the important role of Pd(0) quinone complexes.

Oxidation of adamantane by palladium acetate systems

Beattie, James K.,MacLeman, Susan,Masters, Anthony F.

, p. 99 - 102 (1999)

Only low yields have been found for the oxidative substitution of adamantane catalysed by diacetatopalladium(II) in trifluoroacetic acid. Addition of copper(II) acetate produced a significant increase in conversion, exclusively to 1-adamantanol. The addition of potassium persulfate gave even higher yields, but at the expense of selectivity, with some 2-adamantanol product.

The synthesis and crystal structure of [Pd(C2H3O 2)2]n was analyzed. X-ray powder diffraction technique was used to determine the crystal structure of the compound. It was found that palladium acetate complexes were connected into a polymeric in which two Pd atoms were bridged by two acetate groups. It was observed that Pd atom occupied the special position (0,1/2,1/2) and formed rows with a Pd....Pd distance of 2.9192(I)A.

Palladium(II)-catalyzed oxidation reactions represent an important class of methods for selective modification and functionalization of organic molecules. This field has benefitted greatly from the discovery of ancillary ligands that expand the scope, reactivity, and selectivity in these reactions; however, ancillary ligands also commonly poison these reactions. The different influences of ligands in these reactions remain poorly understood. For example, over the 60-year history of this field, the PdII/0 redox potentials for catalytically relevant Pd complexes have never been determined. Here, we report the unexpected discovery of (L)PdII(OAc)2-mediated oxidation of hydroquinones, the microscopic reverse of quinone-mediated oxidation of Pd0 commonly employed in PdII-catalyzed oxidation reactions. Analysis of redox equilibria arising from the reaction of (L)Pd(OAc)2 and hydroquinones (L = bathocuproine, 4,5-diazafluoren-9-one), generating reduced (L)Pd species and benzoquinones, provides the basis for determination of (L)PdII(OAc)2 reduction potentials. Experimental results are complemented by density functional theory calculations to show how a series of nitrogen-based ligands modulate the (L)PdII(OAc)2 reduction potential, thereby tuning the ability of PdII to serve as an effective oxidant of organic molecules in catalytic reactions.

Palladium(II)-catalyzed oxidation reactions exhibit broad utility in organic synthesis; however, they often feature high catalyst loading and low turnover numbers relative to non-oxidative cross-coupling reactions. Insights into the fate of the Pd catalyst during turnover could help to address this limitation. Herein, we report the identification and characterization of a dimeric PdI species in two prototypical Pd-catalyzed aerobic oxidation reactions: allylic C?H acetoxylation of terminal alkenes and intramolecular aza-Wacker cyclization. Both reactions employ 4,5-diazafluoren-9-one (DAF) as an ancillary ligand. The dimeric PdI complex, [PdI(μ-DAF)(OAc)]2, which features two bridging DAF ligands and two terminal acetate ligands, has been characterized by several spectroscopic methods, as well as single-crystal X-ray crystallography. The origin of this PdI complex and its implications for catalytic reactivity are discussed.
