The polarity of free radical intermediates has a profound impact on their reactivity and selectivity. To quantify this effect and predict its outcomes, the Nagib research group at Ohio State University calculated the electrophilicity/nucleophilicity of over 500 types of free radicals. The figure also includes a simple “rule of thumb” for qualitatively predicting free radical … Read more
