Aminierung und para‐C–H‐Arylierung von Arylfluoriden vermittelt durch α‐Methylnaphthyl (MeNAP)‐Palladium‐Katalysatoren

open access: yesAngewandte Chemie, EarlyView.
Katalysatoren, die aus dem halogenverbrückten Methylnaphthyl‐Palladium‐Dimer [Pd(1‐MeNAP)Br]2 und Biarylphosphin‐Liganden in Kombination mit der Base LiHMDS generiert werden, katalysieren Buchwald‐Hartwig‐artige Aminierungen und para‐C–H‐Arylierungen von nicht‐aktivierten Arylfluoriden bereits bei 60 °C.

Consumer Adoption of Internet of Things

open access: yesJournal of Consumer Behaviour, Volume 24, Issue 2, Page 673-693, March 2025.
ABSTRACT The Internet of Things (IoT), a pivotal technology in enhancing user connectivity, faces a paradox: its widespread potential yet limited consumer adoption. This study addresses this dichotomy by synthesizing a large‐scale meta‐analytic structural equation modeling (MASEM) and hierarchical linear meta‐analysis (HiLMA) of 2736 effect sizes from ...

Larvicidal Activity of Phytochemicals From Handroanthus impetiginosus Seeds Against Culex quinquefasciatus

open access: yesChemistry &Biodiversity, EarlyView.
The hexane extract was obtained from the seeds of H. impetiginosus, from which fatty acids and FAMEs were obtained. The three samples were tested on C. quinquefasciatus larvae, promoting mortality with moderate LC50 values. The hexane extract was analyzed by gas chromatographymass spectrometry (GC‐MS), and the most abundant compounds were ethyl oleate (

Impact of Species, Growth Conditions, and Plant Processing on the Phytochemistry and Antimicrobial Activity of Agrimonia Extracts

open access: yesChemistry &Biodiversity, EarlyView.
Agrimony is a medicinal herb known for its content of polyphenols and beneficial bioactivity, both of which can be strongly influenced by cultivation and processing. This study reveals that agrimony plant structures, species, and postharvest processing are the main drivers of observed variability in both phytochemical composition and antimicrobial ...
