1. Basic Info
Name: Palladium(II) acetate
Alias: Palladium diacetate, Pd(OAc)?
CAS No.: 3375-31-3
Molecular Formula: Pd(C2H3O2)2
Molecular Weight: 224.51
2. Physical & Chemical Properties
Physical Properties
- Appearance: Orange-brown crystalline powder
- Odor: Faint acetic acid odor
- Solubility: Soluble in chloroform, dichloromethane, acetone, toluene; slightly soluble in ethanol; insoluble in water, hexane
- Melting Point: Decomposes at ~205 ℃ without clear melting point
- Density: ~2.0 g/cm3
- Hygroscopy: Slightly hygroscopic; hydrolyzes slowly in humid air
- Crystal feature: Exists as trimer cluster Pd?(OAc)? in solid and solution state
Chemical Properties
- Structure: Trimeric palladium carboxylate complex, bridging acetate ligands linking three Pd(II) centers
- Catalytic activity: Universal Pd(II) precatalyst for cross-coupling reactions
- Reduction property: Easily reduced to metallic Pd(0) by phosphines, alkenes, alcohols, hydride reagents
- Ligand exchange: Acetate groups readily displaced by phosphines, amines, halides, N-heterocyclic carbenes
- Hydrolysis: Contact with water slowly generates palladium oxide precipitate and acetic acid
- Thermal decomposition: Above 200 ℃ decomposes into Pd metal, CO?, acetone, acetic acid vapor
- Photostability: Darkens under prolonged light exposure; store light-proof
- Compatibility: Compatible with anhydrous organic solvents; incompatible with water, strong reducing agents, ammonia, strong alkali
3. Main Application Fields
1. Organic Synthesis Catalyst (Core Application)
