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
本文介绍了在微波辐射下,在水存在下,由 O-烷基烷基膦酰氯 2a-j 与 4-二甲氨基吡啶 (DMAP) 合成 O,O-二烷基二烷基焦膦酸盐 (DADAPP) 的一锅无溶剂微波辅助合成方法。该反应由鏻盐发生,鏻盐转化为 DADAPP 4a-j。这些 DADAPP 是化学战剂沙林、梭曼和 VX 及其类似物的重要标志。与传统方法相比,该方法具有操作简单、产率高、反应时间短等优点。
