Hydride Nitrides: Crystal Structure Redetermination of LiSr2H2N and the Isostructural LiBa2H2N
European Journal of Inorganic Chemistry, EarlyView.The quaternary hydride nitrides LiSr2H2N and LiBa2H2N are obtained in a non‐centrosymmetric crystal structure, different from previous reports. Crystal growth of the honey‐ and pale‐yellow compounds and essentially single phase synthesis is successful using alkali metal flux. The resulting fully ordered structures do not account for a structural reason

European Journal of Organic Chemistry, EarlyView.A Rh(III)‐catalyzed [4 + 2] annulation of 2‐aryl imidazoles/benzimidazoles with α‐diazocarbonyl compounds is developed for the synthesis of π‐conjugated imidazo/benzimidazo[2,1‐a]isoquinolinones systems. Mechanistic studies and control experiment reveal that the reaction proceeds via imidazole‐directed ortho C(sp2)–H activation, followed by carbene C–H

Feminist Anthropology, EarlyView.Abstract This article examines how mobility restrictions imposed by governments during the COVID‐19 pandemic intensified reproductive and mobility injustices. It traces shifting configurations of privilege and inequality within marginalized groups whose reproductive desires remain legally and socially unrecognized.

Journal of Heterocyclic Chemistry, EarlyView.Isolation and characterization of Se‐brominated Hügerschoff intermediates enable structural and mechanistic insight into seleno‐Hügerschoff cyclization to 2‐aminobenzoselenazoles. ABSTRACT A brominated intermediate within the Hügerschoff reaction has long been postulated but never directly observed.

People and Nature, EarlyView.Abstract Longer‐term perspectives—equivalent to the lifespans of long‐lived trees—are required to fully inform perceptions of ‘naturalness’ used in woodland conservation and management. Stand‐scale dynamics of an old growth temperate woodland are reconstructed using palaeoecological data.
