Advanced Synthesis &Catalysis, Volume 365, Issue 15, Page 2643-2650, August 10, 2023., 2023 Abstract In this study, 3H‐phenothiazin‐3‐one is identified as a photocatalyst for the photochemical oxidation of sulfides to sulfoxides. This photocatalytic method uses a low catalyst loading (0.05 mol%), molecular oxygen as the sole oxidant, and a blue LED lamp as the irradiation source. It can be applied to the oxidation of both alkyl‐aryl and alkyl‐

Photochemical Aminochlorination of Alkenes without the Use of an External Catalyst
Chemistry – A European Journal, Volume 29, Issue 45, August 10, 2023., 2023 Photochemical aminochlorination of alkenes: Appropriate tuning of the irradiation wavelength leads to a mild photochemical protocol for the aminochlorination of alkenes, bypassing the need of an external photocatalyst or the use of the more labile N−I or N−Br starting materials for the 1,2‐aminohalogenation reactions.

Observing Genre in Archaic Greek Skolia and Vase-Painting [PDF]
, 2016 This paper reexamines the generic morphology of the skolion melos, offering a more focused definition of the genre than has previously been admitted. As the accumulated evidence shows, the skolion was recognized as a distinct lyric genre in antiquity, defined largely by its sympotic occasion, but also a tendency toward gnomic content and a unique ...

Photochemical Aerobic Upcycling of Polystyrene Plastics
ChemSusChem, Volume 17, Issue 20, October 21, 2024.A photochemical aerobic upcycling protocol of polystyrene plastics to benzoic acid was introduced. A synergistic catalytic system of 2,4‐diethylthioxanthone with N‐bromosuccinimide under 390 nm irradiation led to excellent results. Abstract Although the introduction of plastics has improved humanity's everyday life, the fast accumulation of plastic ...

Direct Diels‐Alder Reaction of Biomass‐Derived Furfurol with Maleimides in a Bio‐Based Green Solvent
European Journal of Organic Chemistry, Volume 27, Issue 15, April 15, 2024.The upconversion of biomass‐derived furfurol through a direct Diels‐Alder reaction with maleimides in 2‐Me‐THF enabled the construction of various heterocyclic compounds, while switching the reaction selectivity depending on the temperature. Abstract Environmental concern has motivated an inclination to exploit waste and upgrade it into high‐added ...

Voice of the People: Popular Symposia and the Non-Elite Origins of the Attic Skolia
Transactions of the American Philological Association, 2014summary: This paper reexamines the known performance contexts of the skolion in light of recent advances in our understanding of sympotic demographics and Greek popular culture, providing a close reading of select songs. In showing that the genre was primarily associated with public festivals and non-elite symposia, I argue that the Attic skolia ...
