Phosphine,dicyclopentyl- - Introduction
Dicyclopentylphosphine is an organophosphorus compound with the chemical formula C10H19P. It is a colorless liquid with a pungent odor. The following is a description of the nature, use, preparation and safety information of the Dicyclopentylphosphine:
Nature:
- Dicyclopentylphosphine is a colorless liquid, not volatile at room temperature, but can be vaporized.
-It is soluble in organic solvents such as ethers, alcohols and hydrocarbons.
- Dicyclopentylphosphine is weakly alkaline and can react with acid.
Use:
- Dicyclopentylphosphine is usually used as a ligand in metal-catalyzed reactions, which can form stable complexes and promote the catalytic reaction.
-It is used as a reducing agent and nucleophile in organic synthesis, and is often used to reduce aromatic ketones and ketones.
- Dicyclopentylphosphine can also be used to synthesize a variety of organic phosphorus compounds, such as phosphene and cysteine phosphate.
Preparation Method:
- Dicyclopentylphosphine can be obtained by reacting cyclopentyl magnesium bromide with triphenylphosphine. In methyl chloride, cyclopentyl magnesium bromide is added first, then triphenylphosphine is added, and the reaction is Dicyclopentylphosphine.
Safety Information:
- Dicyclopentylphosphine have a pungent odor and may cause irritation to the eyes, skin and respiratory tract when in contact.
-Prolonged or heavy exposure may have health effects. Prolonged inhalation, ingestion or contact with skin should be avoided.
-Pay attention to personal protective measures when using, such as wearing gloves and safety glasses.
-Waste shall be disposed of in accordance with local regulations and shall not be discharged at will.
