Chemical Properties |
Colorless to light yellow liqui |
|
Uses |
Di-tert-butylchlorophosphine is associated with palladium(II) acetate and used in Suzuki-Miyaura cross-couplings of arylboronic acids with aryl bromides and chlorides. It serves as a ligand and used in the preparation of mono- and bidentate phosphine ligands in metal complexes for catalytic chiral asymmetric hydrogenations. Further, it is used in asymmetric and transition metal coupling reactions. In addition to this, it plays an important role in the preparation of other phosphines in catalytic polymerization reactions. |
|
Application |
Bulky ligand used with Pd(OAc)2 in efficient Suzuki-Miyaura cross-couplings of arylboronic acids with aryl bromides and chlorides. |
|
Precautions |
Air and moisture sensitive. Keep the container tightly closed in a dry and well-ventilated place. Incompatible with strong oxidizing agents and strong reducing agents. |
