Abstract :
We describe here the dynamic 1H NMR studies of dimethyl 2-(triphenylphosphoranylidene) succinate (1). Phosphorane 1 has a bond presenting slow (in the 1H NMR time scale) rotation which results in spectra of two isomers at the same time. From the spectral data were calculated the rate constant and thermodynamic parameters for the rotational process.
