“…The aim of this work was to study the conformational structure and dynamics of a new quaternary phosphonium salt and to compare the results of this study with previously obtained data for similar compounds. One of the most powerful techniques for conformational and dynamic studies of relatively small molecules is the dynamic NMR method . Recently, we investigated the conformational rearrangement of some phosphorus‐containing pyridoxine derivatives with dimethyl (Fig.…”

A novel phosphonium salt based on pyridoxine was synthesized. Conformational analysis of the compound in solution was performed using dynamic NMR experiments and calculations. The obtained results revealed some differences in the conformational transitions and the energy parameters of the conformational exchange of the studied compound in comparison to previously reported data for other phosphorus-containing pyridoxine derivatives. It was shown that increasing the substituent at the C-11 carbon leads to greater differences in the populations of stable states and the corresponding equilibrium energies.
