DIPHENYLPHOSPHINE POTASSIUM SALT - Introduction
Potassium diphenylphosphide(Potassium diphenylphosphide) is an organophosphorus compound with the chemical formula C12H10KP. The following is a description of the nature, use, preparation and safety information of Potassium diphenylphosphide:
Nature:
-Appearance: White or light yellow crystalline powder.
-Solubility: Soluble in organic solvents, such as ether and dimethylformamide.
-Stability: Stable in air.
-Melting point: about 140-145°C.
Use:
-As a catalyst: Potassium diphenylphosphide can be used as a chiral catalyst for asymmetric catalytic reactions to promote the formation of carbon-carbon bonds and carbon-nitrogen bonds.
-Synthesis of organic compounds: Potassium diphenylphosphide can be used to synthesize organic phosphorus ligands, fluorescent probes and photosensitive compounds.
-Chemical research: Potassium diphenylphosphide has a wide range of applications in organic synthesis, catalytic reactions and organometallic chemistry.
Preparation Method:
-reaction materials: diphenyl tetrahydrofuranone, potassium hydroxide and lithium (or sodium) tablets.
-Preparation step: First, diphenyl tetrahydrofuranone is reacted with potassium hydroxide to generate potassium diphenyl alkoxide (Potassium phenolate). The potassium diphenyl alkoxide is then reacted with the lithium (or sodium) sheet to form the Potassium diphenylphosphide.
Safety Information:
- Potassium diphenylphosphide are generally relatively safe under normal use conditions, but the following matters still need to be paid attention:
-Use the appropriate protective equipment such as chemical protective gloves, goggles and protective clothing.
-Avoid inhaling the powder or contact with skin and eyes. If contact is made, rinse immediately with plenty of water.
-should be stored in a dry, well-ventilated place, away from fire and organic matter.
-For safe handling and handling of chemicals, refer to the relevant safety data and operating manuals.
