Observing Genre in Archaic Greek Skolia and Vase-Painting [PDF]

open access: yes, 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 Aminochlorination of Alkenes without the Use of an External Catalyst

open access: yesChemistry – A European Journal, Volume 29, Issue 45, August 10, 2023., 2023
The niche field of photochemistry offers opportunities that are not found in “traditional” ground state chemical pathways. Aminochlorinated derivatives are an interesting family of 1,2-difunctionalised compounds that provide access to a variety of ...

3H‐Phenothiazin‐3‐one: A Photocatalyst for the Aerobic Photochemical Oxidation of Sulfides to Sulfoxides

open access: yesAdvanced 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 Aerobic Upcycling of Polystyrene Plastics

open access: yesChemSusChem, 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 ...
