The pyrethrins and related compounds. Part 21. Carbon-13 nuclear magnetic resonance spectra of synthetic pyrethroids
Abstract
The 13C n.m.r. spectra of a range of synthetic pyrethroids are assigned. Spectra of esters are generally similar to the combined spectra of the component acids and alcohols, and shifts show consistent trends with changes in substituent and stereochemistry, modified in some cases by small through-space effects between distant groups.
