Charge Makes a Difference: Molecular Ionic Bismuth Compounds
Angewandte Chemie, Volume 135, Issue 24, June 12, 2023., 2023 Charged molecular bismuth species encompass cationic and anionic complexes with organic and inorganic ligand spheres as well as ligand‐free molecular clusters. This review provides an overview of their syntheses, structures, and bonding modes. It outlines how the heavy metal bismuth, with its capability of forming non‐toxic compounds, can be understood

European Journal of Organic Chemistry, Volume 26, Issue 47, December 13, 2023., 2023 Starting from a modified Bachmann procedure, which is commonly used for the synthesis of RDX and HMX, two new nitro esters were synthesized and investigated, 1,3‐dinitroxy‐2‐nitrazapropane and 1,7‐dinitroxy‐2,4,6‐trinitrazaheptane. Furthermore, the structural similar compound 1,3‐dinitroxy‐2‐oxapropane was obtained.

Agronomy Journal, Volume 115, Issue 6, Page 2979-2989, November/December 2023., 2023 Abstract Weeds can influence the economics of alfalfa (Medicago sativa L.) production by reducing forage yield and nutritive value or by contaminating hay. Field studies were conducted in Idaho in 2021 and 2022 to evaluate the effect of weed control treatments on alfalfa forage accumulation, weed biomass, and nutritive value.

Melt Castable Derivatives of Pentaerythritol Tetranitrate
Chemistry – A European Journal, Volume 29, Issue 22, April 18, 2023., 2023 Energetic materials: In this work, the pentaerythritol backbone was modified with amine, nitramine and tetrazole functionalities leading to powerful melt castable pentaerythritol tetranitrate derivatives that outperform TNT. Exciting insights into the influence of these functionalities on mechanical sensitivities and melting behavior are observed and ...

Terminal Au−N and Au−O Units in Organometallic Frames
Chemistry – A European Journal, Volume 29, Issue 8, February 7, 2023., 2023 Landscape beyond the oxo‐wall. The terminal auronitrene and auroxyl species [(CF3)3AuN]− and [(CF3)3AuO]− are identified as local minima by calculation and experimentally detected by tandem mass spectrometry (MS2) in the gas phase. These open‐shell species defy the standard rules to assign oxidation states since the unpaired electrons are located on ...
