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