Acetic acid (CH$_3$COOH) has been detected mainly in hot molecular coreswhere the distribution between oxygen (O) and nitrogen (N) containing molecularspecies is co-spatial within the telescope beam. Previous work has presumedthat similar cores with co-spatial O and N species may be an ...
Monitoring of the levels of 5-hydroxyindole-3-acetic acid (5-HIAA) is of significant importance for diagnostics of carcinoid tumors. We propose simple catalytic electrochemical sensors for the determination of 5-HIAA in urine using laccase and its mimetics. Laccase-like nanozymes (LacNZs) were syn...

However, by screening various Lewis acids, stannous triflate was identified as a particularly efficient reagent for this and related Lewis acid-assisted ring-opening reactions of cyclopropyl ketones in the presence of Ac2O, and even catalytic amounts of Sn(OTf)2 (5 mol-%) proved to be ...
