The production of ethylen tially attractive, since the carbon source than petrol bonylation using methyl f used as the catalyst. Met were formed along with of formaldehyde source, r paraformaldehyde, 1,3,5-t The highest yields of met as the source of formalde and limited the rate of ca the highest yields of meth produce these products at methanesulfonic acid is a the reactive intermediates

Hauptgruppen: Erdalkalimetalle werden in der Kugelmühle die Mangel genommen; eine etablierte Aluminium(I)-Verbindung bekommt ein facettenreiches Add-On; Bismut-Radikalgenerator schmeißt den Turbo an, und SO2+-Ionen spalten C-F-Bindungen. Nebengruppen, Bioanorganik Koordinationschemie: Der erste Lösung beobachtbare σ-Methankomplex; Rekorde für Magnetisches-Blocking-Temperatur; Titan hilft, Ethyl...

Visible spectrophotometry is used to study the kinetic of ligand exchange in the system Cu(salpn)/H2salen with or without triethylamine (NEt3) and H2O in acetonitrile solvent at 25 ± 0.1°C and 0.01 M NaNO3 (H2salen and H2salpn are N,N'-ethylen-bis(salicylaldimine) and N,N'-propylen-bis(salicylaldimine), respectively). It is found that the reaction rate is first-order with respect to Cu(salpn). ...

Die Elektroreduktion von CO2 zu Acetat ist eine vielversprechende Strategie zur Speicherung erneuerbarer Energie, jedoch fällt normalerweise als Nebenprodukt an. Pei-Qin Liao und Mitarbeiter berichten in ihrer Zuschrift (e202206470) über ein kovalentes organisches Gerüst mit isolierten aktiven Zentren für die hochselektive Acetat. Das aktive Kupfer-Phthalocyanin-Zentrum hoher Elektronendichte b...
