Chemical Reactions of Amines:Amines are organic compounds that have the functional group \( – {\rm{N}}{{\rm{H}}_2}\). Amines are derived from ammonia. Substitution of alkyl or aryl group for a hydrogen atom in ammonia leads to the formation of alkyl amines and aryl amines, respectivel...
Sustainable Approaches to Photo-, Thermo-, and Electro-Chemical Reactions of AminesInorganic chemistry.Physical chemistry.Materials science.Sustainability.In recent years, sustainable routes for chemical synthesis have garnered renewed interest. As the world continues to fight pollution and rising costs, ...
The mechanism of the reactions of (dialkylamino)ethynylphosphonates with amines is discussed.doi:10.1134/S1070363206060090S. G. SemenovA. V. AleksandrovaA. V. DogadinaYu. F. SigolaevB. I. IoninRussian Journal of General Chemistry
Well-defined conjugates between two amine-containing molecules are more reliably prepared by thiolating one or more amines on one of the biomolecules and converting one or more amines on the second biomolecule to a thiol-reactive functional group such as a maleimide or iodoa...
Electrolysers can upgrade CO2 into high-value chemicals, but there are few tools capable of tracking the reactions that occur within these devices during operation. Now an electrolysis optical coherence tomography platform has been developed to visualize the electrochemical conversion of CO2 to CO, pl...
First of all, synthetic chemistry, which possesses a large experimental material on chemical reactions, namely, knowing what reactants under which conditions are transformed into these or other products. The structure of matter provides necessary data on the structure of particles, interatomic dis...
Amines with free N–H groups have long posed a tremendous challenge in transition metal-catalysed amination reactions. Now, use of a bidentate phosphorus ligand enables the palladium-catalysed oxidative amination of simple olefins with Lewis basic amines, with no prefunctionalization, forming both alkyl...
This method was also used for the synthesis of graphene–Au nanostructure. The researchers used direct chemical reduction of Au precursor (HAuCl4) in the presence of GO or rGO sheets with reducing agents such as amines, NaBH4, and ascorbic acid. Elsewhere, a snowflake-shaped Au nanostructure ...

Interrupted reactions reroute established processes to new and often unanticipated end points. Of particular interest are the cases in which a known reactive intermediate takes on a new reaction pathway, either because this pathway is lower in energy or because the conventional pathway is no longer ...
