Reactions of radical anions. Part XVI. Interpretation of the hyperfine coupling constants of 31P nuclei in phosphorus-containing radical anions
Abstract
We have correlated the observed phosphorus coupling constants of five radical anions obtained from phosphine derivatives with the calculated spin densities, and find that dπ–pπ interactions account satisfactorily for the results whereas pπ–pπ interactions give results very different from those observed.
