摘要: Abstract Pyrophosphonic acids were prepared by partial hydrolysis of phosphonic acid dichlorides and de-hydration acids, respectively. The pyrophosphonic as well their ammonium salts characterized NMR spectroscopy. geminal coupling constant 2JPOP was obtained from spectral analysis its sign determined spin tickling experiments. Furthermore, semiempirical quantum chemical calculations carried out.
