English description（英文原文，共 1406 字符）
Product Name:Triphenylphosphine resin
English Name:Triphenylphosphine resin
CAS No.:39319-11-4
Aliases:Polystyrene-bound triphenylphosphine, Polymer-supported triphenylphosphine, Triphenylphosphine, polymer-bound
Molecular Formula:(C20H17P)n
Physical Properties:White to off-white spherical beads, odorless. Insoluble in water and common organic solvents such as methanol, ethanol and petroleum ether, while it swells well in THF, dichloromethane and toluene. Air-sensitive, slowly oxidized to the corresponding phosphine oxide upon prolonged exposure to air. The crosslinked polystyrene matrix imparts good thermal stability and mechanical strength, with decomposition beginning above 200°C.
Uses:As a polymer-supported triphenylphosphine reagent, it is widely used in Mitsunobu reaction, Appel reaction, Staudinger reaction, Wittig reaction and transition-metal-catalyzed coupling reactions. After the reaction, the reagent can be easily separated from the product by simple filtration, avoiding the difficulty of removing conventional triphenylphosphine, and is especially suitable for automated parallel synthesis and solid-phase organic synthesis.
Technical Specifications:
Phosphorus loading: 1.0-3.0 mmol/g (as triphenylphosphine groups)
Cross-linking: 1%-2% divinylbenzene (DVB)
Particle size: 100-200 mesh (75-150 μm)
Appearance: white to off-white spherical beads
Water content: ≤1.0%
