Cyclic carbonates and their reactions with aminesSix-membered cyclic carbonates (2-oxo-1,3-ioxanes) in which keto or carbohydrocarbyloxy groups are bound to the 5 position of the ring are disclosed. They react surprising quickly with primary or secondary cyclic amines, and the novel product ...
Since amides are readily prepared, their reduction is a favoured method for the making of all amine groups. Reductive Amination of Aldehydes and Ketones Catalytic or chemical reactions in the presence of ammonia or primary or secondary amines may eliminate aldehydes or ketones, resulting in primary,...
(67,68) were obtained in 43 and 37% yield, respectively. It is worth noting the higher reactivity of the corresponding aziridinium intermediates in the case of propargylamines as the homodiaminated products were also formed and their separation was difficult, leading to relatively lower yields...
therapeutic active compounds, the use of the sulfonyloxazolamines as therapeutic active compounds and/or for the production of pharmaceutical preparations in the control of disorders of the central nervous system, a pharmaceutical preparation and the production thereof, and novel compounds of the formula...
Most amine-functionalized adsorbents lose their CO2 capture ability after a few cycles due to dehydration reactions between the amines and CO2-forming urea23. Addressing amine deactivation is thus crucial when considering associated costs and scalability challenges24. Therefore, the development of amine-...

The gas-phase acidity of hindered amines and some reaction chemistry of their corresponding amide ionsGAS PHASE ACIDITIESHINDERED AMINESFA-SIFTION MOLECULE REACTIONSThe gas-phase acidities of three hindered amines have been determined by equilibrium measurements using tandem flowing afterglow-selected-ion...
For example, methods for preparing amines and their reactions are detailed in Sidgewick's "The Organic Chemistry of Nitrogen", Clarendon Press, Oxford, 1966; Noller's "Chemistry of Organic Compounds", Saunders, Philadelphia, 2nd Ed., 1957; and Kirk-Othmer's "Encyclopedia of Chemical ...
