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

A novel series of carbazole-based α-aminophosphonates were synthesized by three component coupling of 6-bromo-9-ethyl-9H-carbazole-3-carbaldehyde, amine and diethyl phosphite using polyethylene glycol (PEG-400) as a green reaction media. The antiproliferative activity of these molecules was evaluated against three cancer cell lines.
