Complete 1H, 13C{1H}, and 31P NMR spectral parameters of some pyrophosphates

The H-1, C-13{H-1}, and P-31 NMR spectral parameters of some pyrophosphates were determined in CDCl3. The most complicated H-1 spectrum can be solved fully only as (A(3)MN)R6XXR6(MNA(3)), where R-6 (= ?N(CH3)(2)) is coupled only to phosphorus (X). Second-order coupling between phosphorus was found and solved with iterative analysis. A signal shape of one of the carbon resonance cannot be explained only with couplings. Explanation for exceptional shape was searched from molecular modeling results. Copyright (c) 2017 John Wiley & Sons, Ltd.
