Continuing from the previous article, this article will continue to introduce the types of free radicals.The Ohio State UniversityNagibproject team summarized the polarities of halogen, sulfur, silicon, and boron free radicals, as well as nitrogen free radicals.See the table below for halogen, sulfur, silicon, and boron free radicals.6。Nagibproject team noted that some effects are also … Read more
Continuing from the previous article, this section will further introduce the types of radicals.The research team from Ohio State UniversityNagibsummarized the polarities of oxygen-centered radicals and sulfur-centered radicals.Oxygen-centered radicals are shown in Table 8. Unlike carbon-centered radicals substituted with oxygen (e.g., α– or β– alcohols), where the influence is determined by polarizability rather than electronegativity, … Read more
Continuing from the previous article, this section will further introduce the types of free radicals.The Ohio State UniversityNagibresearch team summarized the polarities ofnitrogen-substituted carbon-centered free radicals, aryl free radicals, and aromatic compounds with multiple heteroatom substitutions, as well as nitrogen, oxygen, and sulfur-substituted aryl free radicals.The polarity of nitrogen-substituted carbon-centered free radicals is shown in … Read more
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
Continuing from the previous article, this section will further introduce the types of radicals.The research team from Ohio State UniversityNagibhas summarized the polarity of carbon-centered radicals and oxygen-substituted carbon-centered radicals. Carbon-centered radicals:The table below1lists the polarities of various aliphatic radicals.All of these alkyl radicals are more nucleophilic than hydrogen (<2 eV), but key trends can … Read more
