Detection and identification of chemical warfare agents and their precursors/reaction products in various environmental matrices are important tasks which are considered in chemical weapons convention (CWC). 2-[(2-chloroethyl)(alkyl)amino]ethyl alkyl methylphosphonates I and N-alkyl bis(2-(alkoxy-methylphosphoryloxy)amines II are covered under schedule 2.B.4 of CWC and have structures closely related

This article describes a one pot, solvent free, microwave assisted synthesis of O,O-dialkyl dialkylpyrophosphonates (DADAPP) from O-alkyl alkylphosphonic chlorides 2a–j with 4-dimethylaminopyridine (DMAP) in the presence of water under microwave irradiation. The reaction takes place by the phosphonium salts, which are converted into the DADAPPs 4a–j. These DADAPPs are important markers of chemical
