The Role of Photocatalysts in Radical Chains of Homolytic Aromatic Substitutions, Radical Addition to Olefins, and Nucleophilic Radical Substitution Mechanisms
(Royal Society of Chemistry, 2020-08)
Photoinitiated perfluorobutylation reactions of 2-anisidine 1, propenyloxybenzene 2, and 2-mercaptoethanol 3 have been carried out employing commercially available n-C4F9I as the source of C4F9 radicals under three different ...
Complexation of AAPH (2,2′-azobis(2-methylpropionamidine) dihydrochloride) with cucurbit[7]uril enhances the yield of AAPH-derived radicals
(2023)
AAPH (2,2′-azobis(2-methylpropionamidine) dihydrochloride), a water-soluble azo compound is widely employed to produce peroxyl radicals for chemical and biological studies. This compound is shown herein to form a stable ...
Radical fluorination reactions by thermal and photoinduced methods
(Royal Society of Chemistry, 2017-11)
The radical or radical ion-based fluorination reactions of organic compounds will be presented. These methodologies include fluorination processes accomplished through thermal or photoinduced radical/electron transfer ...
