CAS:31277-98-2 | Bis[1,2-bis(diphenylphosphino)ethane]palladium(0)

Bis[1,2-bis(diphenylphosphino)ethane]palladium(0) is an organometallic compound commonly used as a catalyst in organic synthesis. This compound consists of a palladium(0) atom coordinated to two 1,2-bis(diphenylphosphino)ethane (dppp) ligands.

Properties：

1. Appearance: Usually a yellow or light brown solid.
2. Solubility: Soluble in organic solvents such as benzene, toluene and dichloromethane.
3. Stability: Stable under inert atmospheres such as nitrogen or argon, but will slowly oxidize in air, so Bis[1,2-bis(diphenylphosphino)ethane]palladium(0) needs to be handled and stored under oxygen-free conditions.

Uses：

1. Cross-coupling reaction: Bis[1,2-bis(diphenylphosphino)ethane]palladium(0) is widely used in various palladium-catalyzed cross-coupling reactions, such as Suzuki coupling reaction, Heck reaction and Sonogashira coupling reaction. It can effectively promote the formation of carbon-carbon bonds as a catalyst in these reactions.
2. Catalytic mechanism: It usually acts as an active species of catalyst during the reaction. Due to the special properties of its ligand, it can provide moderate electronic and steric effects, promoting reaction selectivity and efficiency.

1. Bis[1,2-bis(diphenylphosphino)ethane]palladium(0) is relatively safe under normal operation. Care should be taken to prevent it from contacting the skin and eyes, and avoid inhaling its powder or vapor.
2. It should be operated under well-ventilated conditions to prevent it from causing combustibles in the air.
3. Dry powder, carbon dioxide or foam fire extinguishing agents should be used for fire extinguishing.
4. When using or disposing of this compound, please follow the relevant safety operating procedures and national regulations.
