2. Physical & Chemical Properties
2.1 Physical Index
- Appearance: White crystalline powder, free-flowing, no agglomeration
- Odor: Odorless
- Solubility: Soluble in DCM, chloroform, toluene, THF, xylene; slightly soluble in methanol/ethanol; insoluble in water, aliphatic alkanes
- Melting Point: 108–112 °C
- Thermal Stability: Stable below 280 °C; decomposes above 320 °C (no normal-pressure boiling point)
- Hygroscopy: Non-hygroscopic, stable under normal atmospheric storage
- Crystal Feature: Uniform microcrystalline solid, easy to weigh and dissolve under anhydrous operation
2.2 Chemical Properties
- Coordination Performance
Forms stable coordination complexes with Pd, Rh, Ir, Pt, Au, Ni transition metals; modulates catalyst selectivity for hydroformylation, hydrogenation, C-C cross-coupling and alkyne cyclization. - Oxidation Resistance
Not easily oxidized to phosphine oxide in air; no special inert gas protection required for short-term handling (long-term storage needs nitrogen sealing). - Acid & Alkali Compatibility
Stable in neutral and weakly acidic media; reacts with strong oxidants to produce tris(pentafluorophenyl)phosphine oxide byproduct; stable under weak alkaline conditions. - Fluorinated Aromatic Reactivity
Perfluorophenyl ring can undergo selective nucleophilic substitution for custom fluorinated fine chemical building blocks. - Thermal Stability
No decomposition under high-temperature catalytic reaction conditions, suitable for industrial continuous catalytic processes.
