Evidence of surface catalytic effect on cosmic dust grain analogues: the ammonia and carbon dioxide surface reaction [PDF]
, 2019 Surface chemistry on cosmic dust grains plays an important role in the formation of molecules at low temperatures in the interstellar and circumstellar environments. For the first time, we experimentally put in evidence the catalytic role of dust surfaces using the thermal reaction CO2 + 2NH3 = NH4+NH2COO-, which is also a proxy of radical-radical ...

Transition Metal Free Cycloamination of Prenyl Carbamates and Ureas Promoted by Aryldiazonium Salts.
Angewandte Chemie, 2018 Upon treatment with aryldiazonium salts, prenyl carbamates and ureas undergo redox-neutral azocycloamination. In general, N-aryl O-prenyl carbamates cyclize in a photocatalytic reaction with visible light and an organic dye.

Atropisomerism of Aromatic Carbamates
Chemistry – A European Journal, 2010 Abstractortho‐Haloarylcarbamates like 1–4 show a high rotational barrier about the Naryl bond of up to 91.6 kJ mol−1 as found for 1, which was determined by 2D exchange NMR spectroscopy (EXSY). It was further demonstrated that the height of the barrier not only depends on the substituents at the axis of chirality, but is also influenced by electronic ...

Interactions of Paraoxonase-1 with Pharmacologically Relevant Carbamates
Molecules, 2020 Mammalian paraoxonase-1 hydrolyses a very broad spectrum of esters such as certain drugs and xenobiotics. The aim of this study was to determine whether carbamates influence the activity of recombinant PON1 (rePON1).
