Diethyl phosphite Chemical Properties,Uses,Production
Chemical Properties
colourless liquid
Uses
Diethyl phosphite is precursor used for the synthesis of various organophosphorus compounds. used to prepare the nickel chloride-diethyl phosphite system, efficient catalyst for the cross-coupling reaction between various functionalized arylzinc halides and aryl bromides, triflates and activated chlorides.
Uses
Diethyl phosphite (DEPI) is a versatile reactive intermediate used in the production of various phosphorus based substances. It may be used to prepare the nickel chloride-diethyl phosphite system, efficient catalyst for the cross-coupling reaction between various functionalized arylzinc halides and aryl bromides, triflates and activated chlorides.
It may be used:
- in the stereoselective synthesis of β-fluorinated alkylphosphonates
- Used in synthesis of homoallylic bromide
- Used in synthesis of series of carbazole-based α-aminophosphonates
- used as an extraction agent and phosphate intermediate.
- Used in synthesis of pesticides kitazine and phosethyl-Al as well as synthetic O, O-diethyl phosphoryl chloride.
- used for the synthesis of plasticizers, flame retardants, etc.
- Diethyl phosphite is reported to be chemical warfare agent (CWA) simulant, simulant for nerve agents sarin, soman, tabun, and VX.
Definition
