Sulfoxaflor reduces food intake and learning efficiency of solitary Osmia bicornis bees

Scientific Reports
Bees in agroecosystems can be exposed to multiple pesticides, such as insecticides and fungicides, but potential sub-lethal consequences on fitness-relevant endpoints like food intake, foraging performance and learning efficiency remain poorly understood.

Efficient copper-induced coupling between NH-fluoroalkylated sulfoximines and aryl iodides or bromides

, 2011
International audienceA high yielding, simple, and flexible copper-based system for N-arylation of fluorinated sulfoximines is reported. Best results were achieved using copper iodide in combination with DMEDA and Cs2CO3 to provide a wide range of N ...

Combined effects of commercial insecticides on survival of the red mason bee Osmia bicornis

Ecotoxicology and Environmental Safety
Insecticides are widely used to control pests, but can also be toxic to ecosystem service providers, including bees. Moreover, their efficacy can increase if they are applied in mixtures.

The synthesis of bioactive sulfoximines and N-alkynylated sulfoximines

, 2014
Compared to sulfone-based drugs, sulfoximine- and sulfilimine-based bioactive compounds are not so common. In order to enlarge the number of sulfoximine-based bioactive compounds, several new potential bioactive sulfonimidoyl derivatives, including bioactive sulfoximine-based acyclic triaryl olefins, sulfoximine- and sulfilimine-based dapsone analogues

Copper-Catalyzed Sulfonylation Reaction of NH-Sulfoximines with Aryldiazonium Tetrafluoroborates and Sulfur Dioxide: Formation of N‑Sulfonyl Sulfoximines

An efficient and practical SO2 insertion protocol of NH-sulfoximines with aryldiazonium tetrafluoroborates and DABSO toward N-sulfonyl sulfoximines has been developed under mildly basic conditions.
