This work describes a method of synthesizing pyrophosphonates, tetraalkyl pyrophosphates and pyrophosphonamidates. Pyrophosphonates can be synthesized by the reaction of alkyl dichlorophosphonate, triethylamine (Et3N), and water, in a molar ratio of 1∶1.2∶0.5 (dichlorophosphonate∶Et3N∶water). When the reaction was allowed to proceed for 15 min in acetone, the maximum yield recorded for the pyrophosphonates was 95%. Et3N was the solvent, with an acid-binding agent. Following this method, the achieved rate of production of tetraalkyl pyrophosphate and pyrophosphonamidate was faster than the rate of production of the compounds reached using traditional methods.

Key words: pyrophosphonates, tetraalkyl pyrophosphates, pyrophosphonamidates, P—O—P bond
