- W2563350710 abstract "The 1 H, 31 P and 13 CNMR spectral parameters of O-ethyl-O-afyl-N-isopropylamidothionophosphates have been measured in CDCl 3 solutions. It turns out that the 31 P chemical, shifts decrease with an increasing of electron-withdrawing abilitya of the para-suhstituents Rin the order, MeO>Me>H>Br>NO 2 ; On the contrary, 1 HNMR shifts of phenyl ring (average shifts of A 2 B 3 system) Increase with an increasing of electron-withdrawing ability of the para-substituents R,Viz.MeO 2 ; And 13 C NMRare without a distinct ofder due to mutual interactions of the two substituents." @default.
