- Synthesis of S-Substituted Benzils and Some Hindered Biphenyls
-
Three methylthio and/or methylsulfinyl substituted benzils (2, 6 and 7) have been synthesized on photo- or thermochemical routes, respectively.Photodecarboxylation of some new different substituted mesityl benzoates (1a-e) leads to hindered biphenyls (3a-e) accompanied sometimes by aldehyde (4a-c) and benzil formation (2) due to compatitive α-cleavage and subsequent stabilization processes of such generated free aroyl radicals.A short summary on constitutional conditions for intramolecular photoredox reactions of ortho functionalized aryl sulfinyl compounds is presented. - Keywords: Photodecarboxylations, α-Cleavages, Photoredox Reactions, Sulfoxides
