Beliefs about collective victimization in contexts of ongoing and historical oppression: A Q methodology study among Kurds from Turkey and Northern Kurdistan in Germany

Political Psychology, Volume 47, Issue 4, August 2026.
Abstract The scarce political and social psychological research on the Kurdish–Turkish context primarily addresses intergroup relations and general perceptions of the conflict. Conversely, Kurds' experiences of and beliefs about collective victimization in this context have not been examined much to date.

Versatile Palladium‐Catalyzed C‐H Arylation of Fluoroarenes with 2‐Chloropyridine Derivatives

Chemistry – A European Journal, Volume 32, Issue 28, 25 July 2026.
Direct C─H arylation of fluoroarenes with 2‐chloropyridines is enabled by a simple Pd/SPhos system in isopropyl acetate. The method uses inexpensive reactants and shows broad scope and high yields. DFT computations explain reactivity and selectivity.

An Aza‐Prilezhaev‐Based Method for Inversion of Regioselectivity in Stereospecific Alkene 1,2‐Aminohydroxylations

Angewandte Chemie, Volume 136, Issue 49, December 2, 2024.
Under acidic conditions (TFA) and in the presence of water, BocNHOTs promotes stereospecific 1,2‐aminohydroxylations of alkenes. The processes involve intermolecular aza‐Prilezhaev aziridination followed by stereospecific SN2‐like opening by water.

Enabling Base‐Free Direct C–H Arylation of Thiophene Derivatives: Glycerol‐Derived Solvents as Active Reaction Media

ChemSusChem, Volume 19, Issue 9, 14 May 2026.
Sustainable glycerol‐based solvents are effective reaction media for the Pd‐catalysed direct CH arylation of thiophene derivatives. Among them, glycerol‐derived ionic liquids act as noninnocent solvents, making the reaction base‐free, and the combination with Pd nanoparticles allows for multicycle process. Nonvolatile glycerol derivatives are employed

Probing Electronic Effects Upon Nucleophilicity and Lewis Basicity of Isothiourea HyperBTM Catalyst Derivatives

ChemistryEurope, Volume 4, Issue 5, May 2026.
Systematic variation of the position and electronic effect of substituents within the benzannulated aromatic part of the HyperBTM catalyst framework indicates that catalysts containing electron‐donating substituents outperform their electron‐deficient variants in terms of rate and enantioselectivity in acylation reactions.
