Synthesis of Diphenyl α-(O-Phenyl Bis(2-Chloroethyl) amidophosphorylamino)-Phosphonates

Abstract

A study on Mannich type reaction synthesis of Diphenyl α-[phenyl N,N-bis(2-chloroethyl) phosphorylamino]methylphosphonates has been carried out. Their geometric stereoisomers were isolated and characterized. The reaction was catalyzed by acetyl chloride and good to excellent yields were obtained under these reaction conditions.

Keywords:

• α-amino phosphonates
• acetyl chloride
• Mannich type reaction
