2. Physical & Chemical Properties
2.1 Physical Index
- Appearance: Bright yellow crystalline powder
- Odor: Odorless
- Solubility: Soluble in THF, DCM, chloroform, benzene, toluene; slightly soluble in methanol; insoluble in water, aliphatic alkanes
- Melting Point: Decomposes above 115 °C without clear melting point
- Hygroscopy: Non-hygroscopic, extremely sensitive to oxygen and light
- Crystal Feature: Fine crystalline solid, fast dissolution in anhydrous deoxygenated organic solvents
2.2 Chemical Properties
- Zero-valent palladium active center: Labile PPh3 ligands, easily dissociates to form coordinatively unsaturated Pd active species to trigger coupling circulation
- Universal coupling catalytic performance: Efficiently catalyzes aryl halide cross-coupling with boronic acid, alkene, alkyne, organotin reagents
- Air & light sensitivity: Gradually turns black under air/light exposure, palladium metal precipitates and loses catalytic activity
- Thermal stability: Ligand dissociation and metal aggregation occur above 100°C
- Acid & Alkali Stability: Stable in neutral anhydrous system; decomposes rapidly in aqueous acid/alkali solution
- Compatibility: Compatible with anhydrous aprotic solvents, phosphine ligands; incompatible with water, air, strong oxidants, concentrated acid
