摘要：

Pyrophosphonic acids were prepared by partial hydrolysis of phosphonic acid dichlorides and by dehydration of phosphonic acids, respectively. The pyrophosphonic acids as well as their ammonium salts were characterized by NMR spectroscopy. The geminal coupling constant 2JPOP was obtained from spectral analysis and its sign was determined by spin tickling experiments. Furthermore, semiempirical quantum chemical calculations of 2/POP were carried out. © 1992, Taylor & Francis Group, LLC. All rights reserved.
