37943-90-1 - Introduction
Diphenyl-2-pyridylphosphine is an organophosphorus compound with the chemical formula C17H14NP. It is a colorless crystalline solid, soluble in organic solvents. Here are some of its properties and uses:
Nature:
1. Diphenyl-2-pyridylphosphine is an inorganic alkaline molecule, which can provide a lone pair of electrons as a ligand to form a complex with metal ions.
2. It is unstable to moisture and air, and long-term exposure to the air should be avoided.
Use:
1. Diphenyl-2-pyridylphosphine is a ligand commonly used in organic synthesis, especially for metal-catalyzed reactions. It can form stable coordination compounds with transition metals and participate in a variety of catalytic reactions, such as hydrogenation, hydrogen transfer, coupling, carbonylation and so on.
2. It can also be used in the research and synthesis of metal organic chemistry.
Preparation Method:
Diphenyl-2-pyridylphosphine are usually synthesized by the following steps:
1. First, acetophenone reacts with H3PO2 to generate an alcohol intermediate.
2. Subsequently, the alcohol intermediate reacts with phosgene in the presence of hydrochloric acid to generate Diphenyl-2-pyridylphosphine.
Safety Information:
1. Diphenyl-2-pyridylphosphine should be careful to avoid contact with air and moisture during operation and storage to avoid oxidation and degradation.
2. it may be toxic and irritating to the human body, when in use should wear protective gloves, glasses and clothing, to ensure good ventilation conditions.
3. waste should be handled in accordance with the provisions of the general chemical waste treatment, to avoid pollution to the environment.
