Abstract: | NMR Spectroscopic Studies of 15N Labelled N-Methyl-imidodiphosphoric Acid Derivatives 15N labelled compounds (EtO)mCl2?m(O)P? NMe? P(O)(OEt)nCl2?n (m = 0–2, n = 0–2) were prepared as a mixture and investigated by means of 31P and 15N NMR spectroscopy. The chemical shift values δP and δN, and the coupling constants 1JPN and 2JPP are discussed and interpreted qualitatively by semiempirical quantumchemical calculations (CNDO/2) using POPLE 'S ΔE-model. |
