2-Biphenylyl(diphenyl)phosphine(CAS: 13885-09-1)

2-Biphenylyl(diphenyl)phosphine is a crystalline solid with a molecular weight of approximately 416.38 g/mol. It has a low solubility in common organic solvents but is readily soluble in toluene and chloroform. This compound is relatively inert under normal conditions but can react with strong oxidizing agents. It is used in various organic reactions and as a ligand in catalysis.

2-Biphenylyl(diphenyl)phosphine is typically synthesized via the phosphination of biphenyl-2-amine using diisopropylethylamine and phosphorus trichloride as reagents. The reaction involves the substitution of a nitrogen atom in biphenyl-2-amine with a phosphorus atom, yielding 2-biphenylyl(diphenyl)phosphine. This synthesis is performed under nitrogen atmosphere to prevent oxidation.

2-Biphenylyl(diphenyl)phosphine is used in the pharmaceutical, polymer, and semiconductor industries. In pharmaceuticals, it serves as a ligand in catalytic reactions. In polymers, it is used to modify polymer properties. In semiconductors, its use is in the development of organic electronic devices and materials.

When handling 2-Biphenylyl(diphenyl)phosphine, it is essential to use appropriate personal protective equipment (PPE) such as gloves and goggles. Work should be conducted in a well-ventilated area or a fume hood to minimize exposure. Spills should be cleaned up using appropriate procedures, and the substance should be stored in a cool, dry place away from direct sunlight and oxidizing agents. Always refer to the Safety Data Sheet (SDS) for detailed instructions.
