6411-21-8 - Introduction

1,2-Bis(diethylphosphino)ethane is an organic compound with the chemical formula C10H23P2, usually abbreviated as dppe. The following is a description of the properties, uses, preparation and safety information of the compound:

Nature:
1,2-Bis(diethylphosphino)ethane is a colorless liquid with a strong odor. It is flammable and can be dissolved in common organic solvents.

Use:
1,2-Bis(diethylphosphino)ethane is widely used as a coordination ligand in organic synthesis and coordination chemistry. It forms complexes with transition metals, and these complexes play an important role in catalytic reactions. For example, it can be used to catalyze hydrogenation reactions, oxidation reactions, disproportionation reactions, coupling reactions, and the like.

Preparation Method:
1,2-Bis(diethylphosphino)ethane can be obtained by the reaction of acetylene and diethyl bromide. In the reaction, diethylphosphonium bromide is treated with alkali to produce diethylphosphonium and then reacted with acetylene to produce 1,2-Bis(diethylphosphino)ethane.

Safety Information:
1,2-Bis(diethylphosphino)ethane needs to be handled with caution during use and storage because it is flammable. Its vapor may cause eye and respiratory irritation, so appropriate protective measures need to be taken during operation. In addition, avoid contact with skin and swallowing. If inhalation or ingestion occurs, seek medical attention immediately.
