Theoretical study of the conformational arrangement of 3-benzylidene-2,4-pentanedione and its substructures

open access: yes, 1983
The quantum chemical PCILO method was employed for calculation of conformational maps of 3-benzylidene-2,4-pentanedione. The analogous conformational maps of simpler substructures were also investigated to enable investigating the respective interactions.

Alkaline‐Earth Metal Complexes Based on Tridentate β‐Diketiminate Ligands Bearing a Tethered Secondary Amine: Synthesis and Characterization

open access: yesZeitschrift für anorganische und allgemeine Chemie, Volume 652, Issue 11, 16 July 2026.
Deprotonotion of a β‐diketiminate ligand with a tethered secondary amine resulted in highly stable heteroleptic complexes, but the formation of the dianionic ligand could not be achieved. The alkaline‐earth (Ae) metal chemistry of a β‐diketiminate (BDI) ligand with a bulky Ar‐substituent and a pendant amine arm was investigated. The ligand precursor HC[

Characterization of Physicochemical Properties, Volatile Compounds, and Sensory Attributes of Tonto, a Traditional Ugandan Banana‐Based Alcoholic Beverage

open access: yesFood Science &Nutrition, Volume 14, Issue 7, July 2026.
Traditional Ugandan Tonto is produced through the spontaneous fermentation of banana juice and roasted sorghum. Fermentation decreased pH and total soluble solids while increasing ethanol and titratable acidity. A total of 38 volatile compounds were identified, with esters contributing characteristic fruity and banana‐like aromas.
