Description

General description

Diethyl phosphite is reported to be chemical warfare agent (CWA) simulant, simulant for nerve agents sarin, soman, tabun, and VX.

Application

Diethyl phosphite 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
• in the synthesis of homoallylic bromide
• in the synthesis of series of carbazole-based α-aminophosphonates
