2-(Di-tert-butylphosphino)-2 '-methylbiphenyl is a commonly used organophosphorus ligand. The following is a description of its nature, use, formulation and safety information:
Nature:
-Appearance: Colorless to pale yellow crystalline solid
-Molecular formula: C20H25P
-Molecular weight: 292.39g/mol
-Melting point: 142-144 ° C
-Solubility: Soluble in many organic solvents
Use:
- 2-(Di-tert-butylphosphino)-2 '-methylbiphenyl is an important ligand, which is widely used in organic synthesis and metal organic chemistry.
-It is often used in transition metal catalyzed reactions in coordination chemistry, such as olefin hydrogenation, olefin isomerization, C- C bond formation and other reactions to act as a ligand.
Method:
