From CO2 to C1 Liquid Fuels: Molecular Electrochemical Production of Formic Acid and Methanol

Angewandte Chemie, Volume 138, Issue 2, 9 January 2026.
Sustainable transformation of CO2 into formic acid and methanol is key to circular carbon economies and sustainable energy. These liquid C1 products are high in energy density, easy to store, and serve as hydrogen carriers and feedstocks. Electrochemical CO2 reduction provides a promising route for carbon recycling and renewable energy integration ...

Bis(2‐Amino‐5‐thienyl)keton als sauerstofftoleranter Sensibilisator für die konventionelle radikalische Photopolymerisation

Angewandte Chemie, Volume 138, Issue 5, 28 January 2026.
Bis(2‐Amino‐5‐thienyl)ketone wirken als Sensibilisator in Mehrkomponenten‐Photoinitiatorsystemen, die entweder Diaryiodonium Kationen oder Aminobenzoate als Co‐Initiatoren verwenden, um eine konventionelle radikalische Polymerisation nach einem oxidativen bzw. reduktiven photoinduzierten Elektronentransferprotokoll zu initiieren.

Morpholines, V

Zeitschrift für Naturforschung B, 1972
A new synthesis has been developed for the hitherto unreported 2-substituted-3-oxo-4H-1,4-oxazines 3b-3j via the cyclodehydrohalogenation of N-aryl-N-dichloroacetyl-2-amino-4′-nitroacetophenones in dimethyl sulfoxide with potassium t-butoxide. The structures of all the oxazine derivatives have been verified by IR and NMR spectroscopy and correlations ...

Bis(2‐amino‐5‐thienyl)Ketone as Oxygen Tolerant Sensitizer for Conventional Radical Photopolymerization

Angewandte Chemie International Edition, Volume 65, Issue 5, 28 January 2026.
Bis(2‐amino‐5‐thienyl)ketones operate as sensitizer in multi‐component photoinitiating systems using either diaryl iodonium cation or amino benzoates as coinitiators to initiate conventional radical polymerization following either oxidative or reduction photoinduced electron transfer protocol, respectively.

Exploration of morpholine-thiophene hybrid thiosemicarbazones for the treatment of ureolytic bacterial infections via targeting urease enzyme: Synthesis, biochemical screening and computational analysis

Frontiers in Chemistry
An important component of the pathogenicity of potentially pathogenic bacteria in humans is the urease enzyme. In order to avoid the detrimental impact of ureolytic bacterial infections, the inhibition of urease enzyme appears to be an appealing approach.

Formylation with "Supercritical” CO2: Efficient Ruthenium-Catalyzed Synthesis of N -Formylmorpholine [PDF]

, 2018
Formylation of morpholine with "supercritical” CO2 using the bidentate ruthenium catalyst RuCl2(dppe)2 affords high N-formylmorpholine production rate at almost 100% selectivity. The solventless reaction could be an interesting alternative to the present

Design, synthesis, in vitro potent antiproliferative activity, and kinase inhibitory effects of new triarylpyrazole derivatives possessing different heterocycle terminal moieties

Journal of Enzyme Inhibition and Medicinal Chemistry, 2019
A new series of triarylpyrazole derivatives having different heterocycle terminal groups have been designed and synthesised. Compounds 1h–j and 1l exhibited the highest mean percentage inhibition against the 58 cancer cell lines at a concentration of 10 ...
